Question

Jake volunteers to help out his younger brother's basketball team in his free time. One of his tasks is to ensure that all the basketballs have enough air in them. Given that a properly inflated basketball measures 8.8 inches across, what is the total volume of air inside six of Jake’s basketballs? Assume that the wall of each ball is infinitely thin.
681.47 cubic inches
1,651.32 cubic inches
3,775.23 cubic inches
5,451.78 cubic inches

Answer 1

A is 681.47

B is 1,651.32

c is 3,775.23

D is 5,451.78

Answer 2

Well, since basketballs are spheres, we can use the formula for the volume of a sphere. The formula is 3/4 x 3.14 x r^3. Since the diameter is 8.8, the radius is 4.4 Can you solve 3/4 x 3.14 x 4.4^3?

Answer 4

Ok, let's start with 4.4^3. Do you know that?

Answer 5

Then, 3/4 x 3.14 x 4.4 x 4.4 x 4.4 ? Same thing, we usually use a calculator for this one.

Answer 6

Wait a second, I just noticed the answer I got from solving the equation I posted wasn't one of the choices. 0 _ 0

Answer 7

im lost :(

Answer 8

Ahh... @AnswerMyQuestions you got the wrong formula, it's not 3/4. It's 4/3*pi*r^3 :)

Answer 9

Ohhh! Yeah! Thanks, @amlim14 .
