3) The volume of a sphere is 7234.56ft9. Find the diameter.

4) The volume of a sphere is 20,833.3ryds. What is the radius?

a) r = 12.001

So diameter is d = 2r

d = 2 * 12.001

d = 24.002 ft²

b) r = 44.345 yrds

Step-by-step explanation:

Volume of sphere

V = 4/3*pi*r³

a) Putting the values

7234.56 = 4/3 * 3.14 * r³

Simplifying

r = 12.001 ft

b) putting the values in the formula of volume of sphere

20833.3 yards = 4/3 * 3.14 * r³

Simplifying

20833.3 yards = 4.86 * r³

Rearranging the equation

r³ = 20833.3 * 4.186

r³ = 87208.1

r = 44.345 yards
