The height of a cone is twice the radius of its base.
amm1812

Answer:

The correct answer is option 1. \frac{2}{3} \pi x^3 cubic units.

Step-by-step explanation:

The formula for the volume, V of a right angled cone is given as:

V = \dfrac{1}{3} \pi r^{2} h ...... (1)

Where, \pi = 3.14

r is the radius of the circular base of the cone.

h is the height of the cone.

We are given that height is twice of the radius of its base.

Let the radius of base = x units

Now, As per the question statement,

The height of cone= 2 \times x units

Putting the values of r, h in equation (1) to find the volume:

\Rightarrow \dfrac{1}{3} \times \pi \times x^{2} \times 2x\\\Rightarrow \dfrac{2}{3}\pi x^{3}

Hence, the correct answer is option 1. \dfrac{2}{3}\pi x^{3} cubic units.
