Find surface area of this cone ​

SA = 200π cm²

Step-by-step explanation:

The surface area is calculated as

SA = area of base + area of curved surface

     = πr² + πrs ( r is the radius and s the slant height )

Using Pythagoras' identity in the right triangle to find s

s² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )

s = = 17

SA = π × 8² + π × 8 × 17

      = 64π + 136π

      = 200π cm²

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
