Question

PLEASE HELP! :(

What is the surface area of the right cone below?

Answer 1

A≈606.32

Explanation:

you need to use this equation: A=πr(r+h^2+r^2) to figure it out...

just plug your length, height, and radius in, and u have ur answer!!

ur answer shud be A≈606.32

Hope this helps!!

Answer 2

The surface area of the right cone is 176π sq unit. Option C.

Explanation:

Given,

The radius (r) of the cone = 8 unit

Slant height (l) = 14 unit

To find the surface area of the right cone.

Formula

The surface area of the right cone = πrl+πr² sq unit

Now,

The surface area of the right cone = π×8×14+π×8² sq unit

= 112π+64π = 176π sq unit.
