a beach ball has a diameter of 10 inches. What is the volume of air contained inside the beach ball? Use 3.14 for pi. Round your
erastova [34]

Answer:

A beach ball is a sphere, so we will need to know how to find the volume of a

sphere. V = 4Pi * (r ^ 3 / 3)

We have the diameter, but not the radius. To find the radius, it is half of the

diameter.

10÷2=5 Now let's plug it in.

4T(5³/3) Let's solve.

4pi = 12.56

5³= 125

125÷3= 41.67 (repeating 6) 41.67x12.56=523.3752

523.33 cubic inches is the volume of

air contained inside the beach ball. The reason I picked that answer is because a repeating 6. So we should expect for

we rounded up to 41.67, when there was

the answer to be a couple decimals lower

from the answer we got. Tell me if this helps!!

Just use y2-y2/x2-x1

so

1+5 (because subtracting a negative is the same as adding a positive)

4-2


6/2

or 3/1 which is the same as 3
