Question

HELP ME PLEASE! 20 POINTS!!!

Answer 1

Answer:

is in the shape of a sphere

diameter = 60 feet

radius = r = 60/2 = 30 feet

Step-by-step explanation:

volume of sphere = 4/3 × π × r³

= 4/3 × π × 30³

=4/3π × 27,000

= 36000π cubic feet

Answer 2

Answer:

36000π cubic feet

Step-by-step explanation:

Given :

• Diameter of sphere = 60 feet

Solving :

• Volume = 4/3πr³
• But 2r = d or r = d/2
• Therefore, volume is :
• ⇒ 4/3π(d/2)³
• ⇒ 4/24πd³
• ⇒ 1/6πd³
• ⇒ 1/6 x 60 x 60 x 60 x π
• ⇒ 10 x 3600π
• ⇒ 36000π cubic feet
