volume of a sphere = 4/3 *pi * r^3
3/4 * pi = 4/3 *pi * r^3
divide each side by pi
3/4 = 4/3 * r^3
multiply each side by 3/4
3/4 * 3/4 = r^3
9/16 = r^3
take the cube root of each side
r = (9/16) ^ (1/3)
Answer:
the distance from home to hardware store = (3030/60) * 88= 4444miles
time to travel back at a speed of 24mph = 4444miles /24mph = 11110 minutes
