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.
