Question

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

Answer 1

Answer:

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

Step-by-step 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

=  $\frac{22}{7}\times 10\times 12.1$

=  $\frac{22}{7}\times 121$

=  $380.28 \ yd^2$

0r,

=  $381 \ yd^2$
