I need help on this one!!! Please helppppppp!

Answer:
Step-by-step explanation:
For pi i use the estimate 3.14
First find the radius of the sphere using the formula circumference= pi * diameter [tex]273=3.14d[/tex]
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 [tex]4\pi r^2[/tex] to get the surface area, which is, rounded to the nearest number, is 23,734 feet
