Question

A sphere has a diameter of 33.2meters. what is its surface area? use 3.14 to approximate pi. round to the nearest hundredth.

Answer 1

3461.03 m²

Explanation:

1. Surface area of sphere= 4πr²

2. Diameter= 2 X radius

3. Radius= diameter/2

4. 33.2/2= 16.6

5. Substitute: 4 x 3.14 x 16.6² = 3461.0336

6. Round to nearest hundredth:

Answer= 3461.03

Answer 2

Explanation:

`S=4\pi r^2=4\pi*((33.2)/(2) ) ^2=4* 3.14*16.6^2=3461.03m^2`
