Question

A cylinder has a radius of 5 cm and a height of 12 cm, what is the volume?

Answer 1

Explanation:

In a cylinder

• Radius=r=5cm
• Height=h=12cm

We know that

`\boxed { \sf \: volume = \pi {r}^(2) h} \\ \rm \rightharpoonup \: (22)/(7) * {5}^(2) * 12 \\ \rm \rightharpoonup \: (22)/(7) * 25 * 12 \\ \rm \rightharpoonup \: (6600)/(7) \\ \rm \rightharpoonup \: 942.8cm {}^(3)`

Answer 2

approx. 943 cm^3

Explanation:

π × 5^2 x 12 = approx. 943 cm^3
