Question

A drinking glass is in the shape of a cylinder. The volume of the glass is 2211.68 cubic centimeters, and its diameter is 16 centimeters. Find the height of the glass.

Round the answer to the nearest centimeter. Include the units in your typed answer.

Answer 1

11cm

Explanation:

diameter = 16, r = 8 (16÷2)

π = 3.142

V=πr2h

2211.68 = π x 8^2 x h

2211.68 = 3.142 x 64 x h

2211.68 ÷ 64 ÷ 3.142 = h

h = 10.9986

= 11 cm (round off to nearest cm)

To check and confirm

V=πr2h

3.142 x 64 (8^2) x 10. 9986 = 2211.68
