saul85 [17]

Answer:

The ratio is 3:8

C = 2 * pi * r

for 9 inches;

C = 2 * pi * 9 = 18 pi inches

For 24 inches;

C = 2 * pi * 24 = 24 pi inches

18 pi : 48 pi

divide through by 6 pi

Zanzabum

Plug in 10 for p and solve for h:

-10+60=h+10000

<em>*Simplify the left side of the equation by adding the terms*</em>

50=h+10000

<em>*Subtract 10000 from both sides*</em>

-9950=h

Hope this helps!!
