Answer:

Explanation:

For pi i use the estimate 3.14

First find the radius of the sphere using the formula circumference= pi * diameter
273=3.14d

then divide both sides of the equation by d to get the diameter, which is about 86.94.

To get the radius, divide the diameter by 2, which equals 43.47.

Use the formula
4\pi r^2 to get the surface area, which is, rounded to the nearest number, is 23,734 feet
