Question

help me how to solve this??

Answer 1

Hey mate,

We know volume of cone = 1/3 * pie * r^2 * h

Now given,

R = H = x cm

So just plugging in the values,

= 1/3*pie*x^2*x

= 1/3*pie*x^3 cm (b)

Hope this helps you out!

Answer 2

Volume of Cone =

$\frac{1}{3} \pi \: {r}^{2} h$

According to the question ,

r = h = x cm

Volume of cone =

$\frac{1}{3} \pi {x}^{2} \times x$

=

$\frac{1}{3} \pi {x}^{3}$

Therefore, your answer is (b)

$\frac{1}{3}\pi {x}^{3}$
