The question is down below

Answer 1

Answer:

C) 132 sq. cm

Step-by-step 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 $\pi\approx\dfrac{22}{7}$

$A\approx42\left(\dfrac{22}{7}\right)=(6)(22)=132\ cm^2$
