A cylinder has a base radius of 10m a height of 18m. What is its volume in cubic

m, to the nearest tenths place?

Answers

Answer:

5656 m^3

Step-by-step explanation:

Volume of a cylinder can be calculated using below formula

V = πr²h

Where

h= height =18m

r= radius= radius = 10m

If we substitute the values we have

V = π × (10)²× 18

= 5655.6 m^3
