Serhud [2]
<span>You paint 1313 of a wall in 1414 hour.
Now we need to find the rate in order you to paint one wall.

1313 : 1414 = 1 : X
1414 = 1313 X
X = 1.08

PLEASE HELP! BRAINLIEST!!!!!!! PLEASE
Gnesinka [82]
Hello!

First you have to find the volume of the cylinder

To find the volume of a cylinder you use the equation

V =  \pi  r^{2} h

V is volume
r is radius
h is height

Put in the values you know and 3.14 for pi

V = 3.14 *  3^{2} * 7

Square the number

V = 3.14 * 9 * 7 

Multiply

V = 197.82
------------------------------------------------------------------------------------------------------
Next you find the volume of the sphere

To find the volume of a sphere you use the equation

V =  \frac{4}{3}  \pi  r^{3}

V is volume
r is radius

Put in the values you know and 3.14 for pi

V =  \frac{4}{3} * 3.14 *  3^{3}

Cube the number

V =  \frac{4}{3} * 3.14 * 27

Multiply

V = 113.04
------------------------------------------------------------------------------------------------------
Finally you subtract the two volumes from each other

197.82 - 113.04 = 84.78
------------------------------------------------------------------------------------------------------
The answer is C)84.78

Hope this helps!
