What is the approximate volume of the composite figure? Use 22/7 for pi. Round to the nearest hundredth. Enter your answer in the box.
Answers
Answer:
188.57 cm³
Step-by-step explanation:
Half sphere = 1/2 volume sphere
Sphere = 4/3 * 22/7 * 3³
Sphere = 4/3 * 22/7 * 27/1
Sphere = 2376/21 = 113.14
113.14 / 2 = 56.57
Cone = 22/7 * 3² * h/3
Cone = 22/7 * 9/1 * 14/3
Cone = 2772/21 = 132
132 + 56.57 = 188.57 cm³

Quandrilateral ABCD is inscribed in a circle. What is the measure of angle A? A=(2x-40)B 116 C D=x what is the measure of angle A
Answers
Answer:
angle A = 88°
Step-by-step explanation:
Given: inscribed quadrilateral ABCD
(recall that inscribed quadrilaterals have opposite angles supplementary.
A=2x-40
B=116
D=x
From inscribed quadrilateral,
B+D=180 => 116+x = 180 => x=64
A=(2x-40) = 2*64-40 = 88°
(C = 180-88 = 92°)
What is the surface area of the cylinder shown? Use 3.14 for pie. 4cm for the Radius, and 9cm for the height.

==============================================
Work Shown:
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*(4)^2 + 2*3.14*4*9
SA = 326.56
Notes:
The answer is approximate. Use more decimal digits of pi to get a more accurate answer (though it will never be exact unless you leave it in terms of pi).The portion 2pi*r^2 is the fact we have two circular bases with area of pi*r^2 each.The portion 2*pi*r*h is the lateral area, or the area around the curved side. If you unfold this portion, as you would maybe a label on a soup can, it has base of 2*pi*r and height h. The base 2pi*r is the circumference of the circle of radius r.Answer:

Use 3.14 for a.
A sphere has a diameter of 4.4 centimeters.
The volume of the sphere is about
cm^3 just
Answers
Answer:
Volume of sphere = 44.57 cm³
Step-by-step explanation:
Given:
Diameter of sphere = 4.4 centimeter
Value of π = 3.14
Find:
Volume of sphere
Computation:
Radius of sphere = Diameter of sphere / 2
Radius of sphere = 4.4 / 2
Radius of sphere = 2.2 centimeter
Volume of sphere = [4/3][π][r³]
Volume of sphere = [4/3][3.14][2.2³]
Volume of sphere = [4/3][3.14][10.648]
Volume of sphere = [1.333][3.14][10.648]
Volume of sphere = 44.568
Volume of sphere = 44.57 cm³
A rectangle has an area of 75.2m2.
One of the sides is 0.8m in length.
Work out the perimeter of the rectangle.
Answers
Answer:
189.6m
Step-by-step explanation:
Area of reactangle= side₁ ×side₂
Let the other side of the rectangle be x meters.
Area of rectangle= 75.2m²
0.8x= 75.2
x= 75.2 ÷0.8
x= 94
Perimeter of rectangle
= 2(side₁ +side₂)
= 2(0.8 +94)
= 189.6 m
In triangle HIJ, N is the centroid. If HK = 10, find KI.
Answers
Given:
In triangle HIJ, N is the centroid and [tex]HK=10[/tex].
To find:
The value of KI.
Solution:
In a triangle, the centroid of the triangle is the intersection of its medians.
Median of a triangle from a vertex divides the opposite side into two equal parts.
It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.
Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.
[tex]KI=HK[/tex]
[tex]KI=10[/tex]
Therefore, the value of KI is 10 units.

Which graph is correct?
Answers
Let's first take a look at our x here. --- (x + 2)^2
Because we are adding a two to our x, this means that we are shifting our graph 2 to the left. Remember that with functions, it's always the opposite!
There is nothing attached to the y, so we are not moving our function up or down.
And then the radius of our circle. Remember that the equation requires us to square this value (... = r^2), so we need to take the square root of 4. The square root of 4 is 2.
With this information, let's now look at our options.
Option A - INCORRECT, the radius is too large
Option B - INCORRECT, this was shifted 2 units to the right
Option C - INCORRECT, the radius is too large
Option D - CORRECT, the radius is 2 and the circle was shifted 2 units to the left
Hope this helps!! :)
Answer:
D
Step-by-step explanation:
The equation for a circle is
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x+2)^2 + (y)^2 = 4
Rewritng
(x- -2)^2 + (y-0)^2 = 2^2
The center is at ( -2,0) and the radius is 2
C and D are the only circles with a center at (-2,0)
B,D are the only circles with radius 2

Answers
Answer:
1 and 2 are equivalent
For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.

Step-by-step explanation:
let the unknown side be x , then
Using Pythagoras' identity in the right triangle
x² + 5² = 17²
x² + 25 = 289 ( subtract 25 from both sides )
x² = 225 ( take the square root of both sides )
x = [tex]\sqrt{225}[/tex] = 15

tanθ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{15}{8}[/tex]

Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:Perimeter of the rectangle =(12s -16t)centimeters.
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+w)
Given that width of the rectangle=(3s+t)centimeters. and
Length of the rectangle=(3s-9t)centimeters.
Solving we have
Perimeter= 2(l+w)
Perimeter=2(3s+t +3s-9t)
Perimeter=2(3s+3s -9t+t)
Perimeter=2(6s-8t)
Perimeter=(12s -16t)centimeters.
