Find the volume of the solid. When​ appropriate, use π=3.14 and round your answer to the nearest hundredth.
Elenna [48]

Answer:

3179.25

Step-by-step explanation:

Hello!

To find the volume of a cylinder we use the equation

V = \pi r^{2} h

V is volume

r is radius

h is height

Put in what we know. It is says to use pi as 3.14

V = 3.14 * 7.5^{2} *18

Solve

V = 3.14 * 56.25 * 18

V = 3179.25

Hope this Helps!
