Answer 1

Hello!

To find the lateral area of a cone you use the equation


`A = \pi r \sqrt{ h^(2) + r^(2) }`

A is area
r is radius
h is height

The radius is have the diameter

Put in the values you know


`A= \pi 80 \sqrt{ 60^(2) + 80^(2) }`

Square the numbers


`A = \pi 80 √(3600+6400 )`\

Add


`A = \pi 80 √(10000)`

Take the square root


`A = \pi 80 * 100`

Multiply 80 and 100


`A = \pi 8000`

Multiply

25133

The answer is
`C)25133 m^(2)`

Hope this helps!
