Answer:
approx 8.5 cm
Step-by-step explanation:
Given:
Volume= 225 cm^2
Diameter= 10cm
∴Radius= 10/2= 5cm
Volume of cone= 1/3 pi r^2 h
(now substitute the values we know),
225 = 1/3 * pi * (5)^2 *h
225*3= 25*pi*h
675= 25*pi*h
675/25= pi*h
27= 22/7*h
h= 27* 7/22
h= 8.5 cm approx.
I have mentioned every minor step. Hope it helps!!
