Question

1. Meghan has to cover only the lateral surface of a cylindrical container of height

12.9 in. and radius 13.6 in. with fabric. To the nearest square unit, calculate how
much fabric does she need? Use a calculator.
A 1,713 in.2
B 2,264 in.2
c 1,102 in.2
OD 1,683 in.2​

Answer 1

Option C
`1,102\ in^(2)`

Explanation:

we know that

The lateral surface area of a cylinder is equal to

`LA=2\pi rh`

we have

`r=13.6\ in`

`h=12.9\ in`

assume

`\pi =3.14`

substitute

`LA=2(3.14)(13.6)(12.9)`

`LA=1,101.76\ in^(2)`

Round to the nearest square inch

`LA=1,102\ in^(2)`
