Question

Volume of right circular cone whose radius is 2/3 of height.
with steps and explanation.

Answer 1

Step-by-step explanation:

Let the radius be r

and height be h

Given that r= (2/3)h ----------- (1)

Now Volume of cone

=(1/3 )×πr^2×h ------------(2)

Substitute the value of r from equation (1) in equation(2)

=(1/3)×π {(2/3)h}^2×h

=(1/3)×π{(4/9)h^2} ×h

=(4/9)×π×h^3

Answer:

(4/9) ×π×h^3
