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

Answer:

r = 6 inch

Step-by-step 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 :

$r=\sqrt{l^2-h^2} \\\\r=\sqrt{10^2+8^2} \\\\r=6\ inch$

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