Question

The radius ‘r’ and volume of a cone and a sphere are equal. Find the height of the cone.

• A. (1/4)r
• B. 4r
• C. (4/3)r
• D. 2r

Answer 1

Answer:

B. 4r

The radius of the cone and the radius of the sphere are equal r cm

according to question,

Given, the volume of cone = volume of the sphere  

$⇒\frac{1}{3}\times{π}\times{r^2}\times{h}$

$=\frac{4}{3}\times{π}\times{r^3}$

⇒ h = 4r
