Question

The total surface area of a cylinder of diameter 10 cm is 330 square centimeters. Find the height of the cylinder?

• A. 10.5 cm
• B. 6.5 cm
• C. 5.5 cm
• D. 2.5 cm

Answer 1

Answer:

C. 5.5 cm

$2\times \pi r \times h=surface area$

$2\times \pi 10 h=330$

$h=\frac{33}{2\pi}$

$h=5.5cm$
