Christine fills a ball in the shape of a sphere with air. The diameter of the ball when it is filled is 18 inches
How much air, in cubic inches, is in the ball when it is filled?

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

10+4√2 is the answer. i dont have the time to explain.

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
