Question

Can someone help me with this? It's volume also. Please help!

Answer 1

D

Explanation:

The formula is area of circle x height

To find area do radius x radius x 3.14 so 49 x 3.14 = 153.86

Since the answer already has pi just do 49 x 10 = 490

Answer 2

Given:

• Radius,r =7cm
• height ,h=10cm

To find out:

the volume of the cylinder

Formula used:

`\pi \: r {}^(2) h`

Solutions:

`volume \: of \: cyli. = \pi * 7 * 7 * 10`

`volume \: of \: cylinder= \red {490\pi}`cm²
