The surface area of a sphere with radius R can be calculated using the formula S=4π·r^2. Write a formula showing r’s dependence on S. (Write r in terms of S.)

Answer 1

S=4πr2 solve for r. divide both sides by 4π.
S/4π= r2 square both sides
sqrt(S/4π)= r plug in your surface area for S

for example:
sqrt(500m2/4π) = r
r = 6.3 meters

Answer 2

i got this anwser but it was wrong? What is the surface area in this case

Answer 3

The equation is supposed to be the awnser, not r=....
