Question

Find the volume of this cylinder.

Give your answer to 1 decimal place.
11 cm
io
14 cm

Answer 1

1330.5

Explanation:

Radius is half of diameter (11), so 5.5 was the other number I plugged in.

Answer 2

1330.5 cm³

Explanation:

The formula for the volume of a cylinder is ...

V = πr²h . . . . . for radius r and height h

The radius of the given cylinder is 1/2(11 cm) = 5.5 cm. Filling in the formula values, we have ...

V = π(5.5 cm)²(14 cm) = 423.5π cm³ ≈ 1330.5 cm³

The volume of the cylinder is about 1330.5 cm³.
