Question

What is the lateral area of the cone? 10 yd and 12.1 yd

Answer 1

The lateral area will be "381 yd²". A further solution is provided below.

Explanation:

The given values are:

Radius of cone,

r = 10 yd

Height of cone,

L = 12.1 yd

As we know,

The lateral surface area of cone is:

=
`\pi r L`

On substituting the values, we get

=
`(22)/(7)* 10* 12.1`

=
`(22)/(7)* 121`

=
`380.28 \ yd^2`

0r,

=
`381 \ yd^2`
