Question

Help me please!

Jack is going to fill his beach ball with water. The radius of the ball is 24 in. How
much water will it take to fill the beach ball?

Answer 1

951.15 ltr

Explanation:

first you convert inch into cm just to make things easier

1 inch = 2.54cm

so,

radius(r)= 24 inch = 24×2.54= 60.96cm≈ 61 cm

then calculate the volume of the sphere

i.e.

V = 4/3(πr³)= 4/3×22/7× 61³= 951158.47 cm³

Now that we have volume

we know that,

1 ltr = 1000cm³

sooo,

• x ltr= 951158.47÷1000= 951. 15 ltr
