Question

A theme park has a ride that is located in a sphere. The ride goes around the widest circle of the

sphere which has a circumference of 489.84 yd. What is the surface area of the sphere? Use 3.14
for
The surface area of the sphere is about yd?.
(Type an integer or decimal rounded to the nearest hundredth as needed.)

Answer 1

76,400

Explanation:

I think this is right, not sure though.

Surface area of sphere:

`4\pi * r {}^(2)`

Circumference :

`2(\pi * r)`

489.84 = 2 × 3.14 × r

2 × 3.14 = 6.28

489.84 = 6.28 × r

radius = 489.84 ÷ 6.28

R =78

Surface Area = 4 × 3.14 × (78)^2

Surface area = 76,415.04

= 76,400
