The volume of a sphere with a radius of 30.5 cm is, 118,786.72 cm³.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
The radius of sphere = 30.5 cm
Now, We know that;
The volume of sphere = 4/3πr³
Where, 'r' is radius of sphere.
Hence, We get;
The volume of sphere = 4/3πr³
The volume of sphere = 4/3 × 3.14 × (30.5)³
The volume of sphere = 118,786.72 cm³
Thus, The volume of a sphere with a radius of 30.5 cm is, 118,786.72 cm³.

Answer: C. The answer i got was C
Answer: 904.32 cm^3
Step-by-step explanation:
The formula to finding the volume of a sphere is (V=4/3(3.14)r^3
So in this case it would be (V=4/3(3.14)(6)^3
The radius is half the diameter so that's how I got 6.
The answer after multiplying everything would be 904.32

The sum of the 1st nth term gp is 127.the sum of the reciprocal is 127/64,if the 1st term is 1.find n and the common ratio
Answer:
Ratio (r) = 2
n = 7
Step-by-step explanation:
The formula for the sum of the nth term of a G.P is given as:
Sn = a(1-r^n)/(1-r)
Where n = Number of terms
r = Common ratio
The sum of the 1st nth term gp is 127.
Hence:
127 = 1(1-r^n)/(1-r)
The sum of the reciprocal is 127/64
The formula is inverted , hence:
Sn = 1/a(1-r^n)/(1-r)
127/64 = r^(1-n)(1-r^n)/(1-r)
Hence:
1/64 = r^(1-n)
r^(n-1) = 64
r^(n-1) = 2⁶
Hence:
r = 2
Solving for n
n - 1 = 6
n = 6 + 1
n = 7
Therefore:
r = 2
n = 7

The Secant of angle A is -5/4. a) What quadrants could angle A be in? b) Determine the measure(s) of angle A
Answer:
a) 2nd and 3rd quadrant
b) 143.13° and 36.87°
Step-by-step explanation:
Secant A = 1/cosecant A
sec A = 1/cosA
If Sec A = -5/4
Cos A = 1/(-5/4)
CosA = -4/5
Since cos A is a negative values, hence the angle A will be in the 2nd and 3rd quadrant
b) If CosA = -4/5
A = arccos(-0.8)
A = 143.13
A = 180 - 143.13
A = 36.87
Hence the measures of angle A are 143.13° and 36.87°

What is the equation in vertex form of a parabola with vertex (-2, -2) that opens downward and is stretched by a factor of 5?
A) f(x) = −5(x + 2)^2 + 2
B) f(x) = −5(x − 2)^2 + 2
C) f(x) = 5(x + 2)^2 − 2
D) f(x) = −5(x + 2)^2 − 2
Answer:
D). -5(x + 2)^2 - 2.
Step-by-step explanation:
Parabola which Opens down and vertex (-2, -2) is :
f(x) = a(x + 2)^2 - 2 where a is negative
Stretch by factor 5 gives:
-5(x + 2)^2 - 2.

Granny needs to paint a Loge made using two right triangles the dimensions Of the loge are shown below what is the difference between the area of the large triangle in the area of a small triangle
Answer:
The difference is
Step-by-step explanation:
Given
Large triangle
[tex]Base = 5cm; Height=9cm[/tex]
Small triangle
[tex]Base = 2cm; Height=6cm[/tex]
See attachment for logo
Required
The difference in their areas
Area is calculated as:
[tex]Area = 0.5 * base * height[/tex]
For the large triangle
[tex]Area = 0.5 * 5cm * 9cm[/tex]
[tex]Area = 22.5cm^2[/tex]
For the small triangle
[tex]Area = 0.5 * 2cm * 6cm[/tex]
[tex]Area = 6cm^2[/tex]
The difference (d) is calculated as:
[tex]d = 22.5cm^2 - 6cm^2[/tex]
[tex]d = 16.5cm^2[/tex]
The value of x is
and the value of y is
Answer:
Y = 50 degrees, X = 60 degrees
Step-by-step explanation:
Since we know that the sum of angles in a triangle is 180 degrees, we can find x easily. We already know that the other two angles are 50 and 70, which adds up to 120, and 180 - 120 is equal to 60 degrees, meaning that x is equal to 60 degrees. Next, to find the measure of y, we first know that the sum of angles on a line is equal to 180 degrees, and if we find the other angle on the line by subtracting 60 + 50 from 180, we can find y. 180 - (60 + 50) = 70 degrees, and since 70 + x + y = 180 and x = 60, we know that x = 180 - (70 + 60) = 50. Therefore, y is equal to 50 degrees.

Question:
Matthew walks 4/10 to mile to Zack's house. Which fraction is equivalent to 4/10?
Answer:
[tex]Fraction = \frac{2}{5}[/tex]
Step-by-step explanation:
Given
[tex]Fraction = \frac{4}{10}[/tex]
Required
Determine its equivalent
To do this, we simplify the fraction
Divide by 2/2
[tex]Fraction = \frac{4/2}{10/2}[/tex]
[tex]Fraction = \frac{2}{5}[/tex]
Hence, 2/5 is an equivalent fraction

a first number plus twice a second number is 8 twice the first number plus the second totals 25
Answer:
The first number is 14
The second number is -3
Step-by-step explanation:
x + 2y = 8
2x + y = 25
Solving simultaneously,
2x + 4y = 16
2x + y = 25
On subtracting, we have
3y = -9
y = -3
Going to substitute for y, we have
x + 2(-3) = 8
x - 6 = 8
x = 14
if 4.5kg sugar cost R36 what will 2.5kg cost
Answer:
Step-by-step explanation:
Find the unit rate of Sugar. Then find the cost of 2.5 Kg sugar
1 kg sugar =36 ÷ 4.5
[tex]= \frac{36*10}{4.5*10}= \frac{360}{45}\\\\= 8[/tex]
2.5 kg of sugar= 2.5 * 8 = 20.0 = R 20
Answer:
Kg Rupee
4.5 = 36
2.5 = ?
Therefore, 2.5*36/4.5
Therefore, 25*36*10/45*10
Therefore, 25*36/45
Therefore, 5*5*36/9*5
Therefore, 5*36/9
Therefore, 5*3*2*3*2/3*3
Therefore, 5*2*2
Therefore, 10*2
Therefore, 20
2.5 kg =20 Rupees
An airplane descends 1.6 miles to an elevation of 8.05 miles. Find the elevation of the plane before its descent.
Answer:
9.65 miles
Step-by-step explanation:
Given:
Final elevation = 8.05 miles
Change in elevation = 1.6 miles
Let Initial elevation which is the elevation before descent = x
Initial elevation - change in = final elevation
(-ve) sign because it was a descent
x - 1.6 = 8.05
x = 8.05 + 1.6
x = 9.65 miles
Hence, elevation before descent is 9.65 miles
2. The volume of a cylinder is 95 cubic centimeters. Which equation
can be used to find h, the height of the cylinderę Circle the correct
answer.
Given:
The volume of a cylinder is 95 cubic centimetres.
To find:
The equation that can be used to find h, the height of the cylinder.
Solution:
We know that, the volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
We know that the base of the cylinder is a circle and the area of the circle is [tex]\pi r^2[/tex]. So, the base area of the cylinder is [tex]B=\pi r^2[/tex].
Now, volume of the cylinder is
[tex]V=Bh[/tex]
The volume of a cylinder is 95 cubic centimetres.
[tex]95=Bh[/tex]
[tex]\dfrac{95}{B}=h[/tex]
[tex]h=\dfrac{95}{B}[/tex]
Where B is the base area of the cylinder.
Therefore, the correct option is G.
