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

Step-by-step 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.
