How do you find radius when given volume for a sphere?

Answer:
v= 4/3 πr³
plug in your known volume and solve for r

if the volume is 1000
1000= 4/3πr³ times by 3 to clear fractions
3000 = 4πr³ divide by 4π on both sides
3000/4π = r³
750/π = r³ now take the cube root of both sides

I plugged this in to a calculator
(750/π )^(1/3) 6.2035 = r the radius
