Question

A cylinder is a radius of 8cm and a volume of 800cm³ calculate it's height and total surface area

​

Answer 1

3.98 cm, 602.18 cm²

Explanation:

Given:

• r= 8 cm
• V= 800 cm³

To find:

• h = ?
• S = ?

Solution:

• V = πr²h
• h = V/πr² = 800/(π8²) = 3.98 cm
• S = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²
