Question

You have a cone with a radius of 4ft and a height of 10ft. Find the area of the triangle formed by a perpendicular cross-section through the cone’s center.

Answer 1

Its 40 because the formula for a triangle is b*h.... i hope i helped

Answer 2

Area of triangle is:

40 square feet

Explanation:

We are given a cone that has radius=4 ft

and height=10 ft

We have to find the area of the triangle formed by a perpendicular cross-section through the cone’s center.

The triangle has base equal to the diameter of the cone=8 ft

(Since, diameter=2×Radius)

and height of triangle=height of cone=10 ft

Hence, Area of triangle=
`(1)/(2)* base* height`

=
`(1)/(2)* 8* 10`

= 40 ft²

Hence, area of triangle is:

40 square feet
