Find the surface area of each figure. round to the hundredths place
Amiraneli [1.4K]

Given:

In the given cone,

Radius of the cone = 7.2 m

Slant height of the cone = 17 m

To find:

The surface area of the cone.

Solution:

The surface area of a cone is:

A=\pi rl+\pi r^2

Where, r is the radius of the cone and l is the slant height of the cone.

Putting \pi=3.14,\ r=7.2,\ l=17 in the above formula, we get

A=(3.14)(7.2)(17)+(3.14)(7.2)^2

A=384.336+162.7776

A=547.1136

A\approx 547.11

Therefore, the surface area of the given cone is 547.11 square m.
