<u>Step-by-step explanation:</u>

Givens:

  • R = 12
  • R = 2r => r = 6

Equations

  1. V = (4/3)(pi)r^3

Find: Vt (Total Volume)

Vt = (1/2)V1 + (1/2)(V2)

Vt = (1/2)(V1 + V2)                 <em>[Factor out (4/3) and (pi) from volumes]</em>

Vt = (1/2)(4/3)(pi)(R^3 + r^3)  <em>[Sub in Values]</em>

Vt = 4071.5 ft^3

kati45 [8]
Trisha - 17 percent
Anchara - 4/25 = 0.16 = 16 percent
Juanita - 16 - 13.3 = 2.7   2.7/16 (since 16 is the total) = 0.16875 = 16.875 percent

So Trisha reduced her time by the greatest percent (17)
