What is the lateral area of the cone to the nearest whole number? The figure is not drawn to
Sveta_85 [38]

Answer:

The lateral surface area of the cone is 25120\ m^2.

Step-by-step explanation:

We have.

Height of a cone is 60 m

Diameter of a cone is 10 m

Radius, r = 80 m

The lateral surface area of a cone is given by :

A=\pi rl

l is slant height of the cone,

l=\sqrt{60^2+80^2} =100\ m

Plugging all values in above formula,

A=3.14\times 80\times 100\\\\A=25120\ m^2

So, the lateral surface area of the cone is 25120\ m^2.
