Question

If a cone has a height of 8 inches and a side measurement of 10 inches, what is the radius of its base?

Answer 1

r = 6 inch

Explanation:

Given that,

The height of a cone, h =8 inches

The slant height of the cone, l = 10 inches

We need to find the radius of the base. The relation between height, radius and the slant height of the cone is given by :

`r=√(l^2-h^2) \\\\r=√(10^2+8^2) \\\\r=6\ inch`

So, the radius of its base is equal to 6 inches.
