A package of modeling clay was shaped like a cone with a radius of 25 cm and a height of 7.2 cm. Miriam used all the clay to make a cylinder with a radius of 15 cm.

What was the height of the cylinder? Express the answer to one decimal place and use 3.14 to approximate pi

25^(2) * 3.14 * 7.2 * 1/3
=4710
cm^(3)
(x the height)

15^(2) * 3.14 * x = 4710
706.5x = 4710
x=4710 divided by 706.5
=6.66666......
,
=6.6 cm
