Question

The question is down below

Answer 1

C) 132 sq. cm

Explanation:

We must calculate the lateral area of a cylinder.

The formula is:

`A=2\pi rH`

r - radius

H - height

We have H = 6 cm and r = 3.5.

Substitute:

`A=2\pi(3.5)(6)=42\pi\ cm^2`

Use
`\pi\approx(22)/(7)`

`A\approx42\left((22)/(7)\right)=(6)(22)=132\ cm^2`
