3) The volume of a sphere is 7234.56ft3. Find the diameter.
pashok25 [27]

Answer: 12.001 ft is the radius

Step-by-step explanation:

Volume of sphere is calculated by following formula:

V = 4/3 pi r³

Putting values

7234.56 = 4/3 × 3.14 ×r³

Simplifying

7234.56 = 4.186 ×r³

Rearranging the equation

r³ = 7234.56/4.186

r³ = 1728.28

Taking cube root on both sides

r = 12.001

Solve for m.
schepotkina [342]
-37m = 12 so u take -37 + 37 = 0 > m = 12 + 37 > m = 49 which isnt one of the choices... u cant divide it and if u do -37 + 12 = -25 that isnt one of the choices either
