Question

A cylinder has a diameter of 10 units. Its radius ___ is units. If its height is twice its radius, its height is____ units. Its volume is about ___cubic units

Answer 1

Answer:

Volume of cylinder is 785.7 square units.

Step-by-step explanation:

Given the diameter of cylinder 10 units. The height is twice its radius. we have to find its volume.

Diameter, d=10 units

⇒ $\text{Radius,}r=\frac{d}{2}=\frac{10}{2}=5units$

Also given height is twice its radius.

⇒ Height=2(r)=2(5)=10 units

$\text{Volume of cylinder=}\pi r^2h=\frac{22}{7}\times 5^2\times 10=785.4 units^2$

hence, volume of cylinder is 785.7 square units.
