Answer:
it's 25 cm
Step-by-step explanation:
Volume = 225π
or πr²h= 225π
or r²h= 225
or h= 225/r²
here diameter d = 6cm so radius r=d/2 = 3cm
or h= 225/3²
hence h= 25cm
Can anyone help me with this math equation?

The diameter of a basketball rim is 18 inches. A standard basketball has a circumference of 30 inches. What is the distance between the ball and the rim in a shot in which the ball goes exactly in the center of the rim? Show your work.
Answer:
4.2 inches
Step-by-step explanation:
Basketball rim:
diameter = 18 inches
r = 18/2 = 9 inches
Ball:
Circumference of ball = 30 inches
2πr = 30 inches
[tex]2*3.14*r = 30\\\\r = \frac{30}{2*3.14}\\\\r = 4.8 inches[/tex]
Distance between the ball and the rim in a shot when the ball goes exactly in the center of the rim = radius of the rim - radius of the ball
= 9 - 4.8
= 4.2 inches
what is the answer to this fraction 4/8+2/8+4/8
Answer:
1 2/8 OR 1 1/4
Step-by-step explanation:
4/8 + 2/8 + 4/8 =
6/8 + 4/8 =
10/8 =
1 2/8 OR 1 1/4

Answer:
QR, QT
Step-by-step explanation:
A radii is a line from the center of the circle to the circumfrence of the circle.
In this case the radii are QR, QT, and QK because they all start from the center of the circle which is point Q and stop at the circumfrence of the circle.
Since QK isn't an answer choice the only answers are ...
QR and QT

What is the area of a square if its side length is 1 173 cm?
Answer:
The number 173 or 1,173?
1,173 x 1,173 = 1,375,929
Since all sides are equal in a square, one given length would be all the side lengths since all sides are equal in a square.
If the side length was 173 then:
173 x 173 = 29,929
i need help i don’t understand my homework?
Please help me with question number 2
Answer:
2. The area of the side walk is approximately 217 m²
3. The distance away from the sprinkler the water can spread is approximately 11 feet
4. The area of the rug is 49.6
Step-by-step explanation:
2. The dimensions of the flower bed and the sidewalks are;
The diameter of the flower bed = 20 meters
The width of the circular side walk, x = 3 meters
Therefore, the diameter of the outer edge of the side walk, D, is given as follows
D = d + 2·x (The width of the side walk is applied to both side of the circular diameter)
∴ D = 20 + 2×3 = 26
The area of the side walk = The area of the sidewalk and the side walk = The area of the flower bed
∴ The area of the side walk, A = π·D²/4 - π·d²/4
∴ A = 3.14 × 26²/4 - 3.14 × 20²/4 = 216.66
By rounding to the nearest whole number, the area of the side walk, A ≈ 217 m²
3. Given that the area formed by the circular pattern, A = 379.94 ft.², we have;
Area of a circle = π·r²
∴ Where 'r' represents how far it can spread, we have;
π·r² = 379.94
r = √(379.94 ft.²/π) ≈ 10.997211 ft.
Therefore, the distance away from the sprinkler the water can spread, r ≈ 11 feet
4. The circumference of the rug = 24.8 meters
The circumference of a circle, C = 2·π·r
Where;
r = The radius of the circle
π = 3.1
∴ For the rug of radius 'r', C = 2·π·r = 24.8
r = 24.8/(2·π) = 12.4/π = 12.4/3.1 = 4
The area = π·r²
∴ The area of the rug = 3.1 × 4² = 49.6.
Can some one awnser the following
Answer:
-11
Step-by-step explanation:
Although you love to watch TV, you have made a goal to spend more time outdoors. You decide that you will spend 222 times as many hours outdoors as you spend watching TV. Write an equation for the number of hours you will spend outdoors, ooo, when you spend ttt hours watching TV.
Answer:
the equation that should be required is 0 = 2t
Step-by-step explanation:
Let us assume the hours of television be t
And, for hours outdoor be o
As the hours outdoors would be twice the hours of television so the equation is
0 = 2t
Therefore the equation that should be required is 0 = 2t
The same is relevant
Answer:
o = 2t
Step-by-step explanation:
You will spend 2 times as many hours outdoors as you spend watching TV. The number of hours you spend outdoors depends on t, the number of hours you spend watching TV.
To find the number of hours you will spend outdoors, o, you can use the equation o = 2t
Remember, you want to find the number of hours you will spend outdoors if you spend 4 hours watching TV and 8 hours watching TV.
8 = 2 x 4
16 = 2 x 8
Now we can turn the values from the equation into ordered pairs in the form (x , y).
The ordered pairs are (4 , 8) and (8 , 16).

-5x+4y=7 y=-2x-8
x = 13, y = 18
hope this is right
Answer:
x=−3 and y=−2
Step-by-step explanation:
-5x+4(-2x-8)=7
-13x-32=7
-13x-32+32=7+32
-13x=39
divide both sides by -13
x=-3
substitute x for -3
-2(-3)-8= -2
y= -2

Answer:
99
Step-by-step explanation:
The following figure is a trapezoid with the following dimensions
Height = 9ft
Shorter Base Length = 6ft
Longer Base Length = 16ft
The area of a trapezoid can be found using this formula
[tex]A=\frac{a+b}{2}h[/tex]
where a and b = bases and h = height
Given all the information needed we plug in the values into the formula
[tex]A=\frac{6+16}{2} 9\\6+16=22\\\frac{22}{2} =11\\11*9=99\\A=99ft^2[/tex]
So we can conclude that the area of the trapezoid is 99 ft²
Answer:
Formula of a trapezoid:
Base 1 + Base 2 x H x 1/2
In this case:
Base 1 (6) + Base 2 (16) x Height (9) x 1/2
= 99

Assuming the point A has coordinates (2,3) and the center of dilation is the origin.
Then the image of point A under a dilation of scale factor of 4 is (4∗2,4∗3)=(8,12)(4*2,4*3)=(8,12)(4∗2,4∗3)=(8,12)
Hence A(2,3)→A′(8,12)A(2,3)\to A'(8,12)A(2,3)→A
′
(8,12)
In general the rule for a dilation of scale factor of k is (x,y)→(kx,ky)(x,y)\to(kx,ky)(x,y)→(kx,ky)
