Answer 1

Answer:

Step-by-step explanation:

V = 1/3 x pi x r^2 x h

=> 9V^2 = pi^2 x r^4 x h^2

c = pi x r x s => s^2  = c^2 / (pi^2 x r^2)

where s^2 = h^2 + r^2

therefore r^2 = s^2 - h^2

therefore  V= 1/3 x pi x (s^2 - h^2) x h

Or, 3V = pi x h x (s^2 - h^2)

Or, 3V x pi x h^3 = pi ^2 x h^4 Xr^2

Or, 3V x pi x h^3 = (pi ^2 x h^2 x r^4)xh^2 / (r^2)

Or, 3V x pi x h^3 = 9V^2 x h^2 / (r^2)

Or, 3V = pi x h x (c^2 / (pi^2 x r^2) - h^2)

Or, 3V = pi x h x (c^2 - (pi^2 x r^2) - h^2)/ (pi^2 x r^2)

Or,
