3. the formula to find the surface area of a sphere is to take the radius of the sphere and square
it and multiply that amount by pi and then multiply that by 4. this is written algebraically as
s=4777, where s is the surface area, r is the radius, and the value of it is 3.14. rewrite the
equation to solve for the radius of the sphere if you know the sphere's surface area. then
estimate the radius of a sphere given a surface area of 500 meters.

Step-by-step explanation:
Surface area of sphere = 4πr²
4πr² = 500
4*3.14*r² = 500
r² =
r² = 500*100/3.14*4*100
r² = 500*100/314*4
r² = 39.80
r =√39.8
r= 6.30 meters
