Question

What is the exact volume of the cylinder?

Answer 1

V = 225 π cm³

Explanation:

V of a cylinder = π · r² · h

r is the radius, yet in the picture is given the diameter.

We know that d= 10 cm and that the radius is half of it so r = 5

h is the height of the cylinder and in the picture is given to be 9 cm

because we are asked to find the exact value we will live pi as a symbol π, rather then change it into a number that will not be exact

V = π · 5² · 9

V = π ·25·9

V = 225 π cm³

Answer 2

V = 706.86 cubic centimeters
`(225\pi )`

Explanation:

`V=\pi r^(2) h=\pi( (10)/(2) )^(2) (9)=225\pi =706.86`

Hope this helps
