V = 4/3 π r³


Given that v = 972π

972π = 4/3 π r³


\\Multiply by 3 on both sides

2916π = 4 π r³


\\ Divide by 4π on both sides

729 = r³


\\cube root both sides

∛729 = r

9 = r


Answer: r = 9 inches

30 feet

Step-by-step explanation:

  • Since Natalie is standing right next to the Penthouse, we can establish the ration between her height and the shadow she casts, which is;

           1.1 : 5.5

  • The two are related by a factor of 1/5
  • We can use this factor to establish the shadow cast by the penthouse;

       1/5 * 150

        = 30
