Question

Find the total surface area of this cone.

Leave your answer in terms of T.
25m
8m
SA = [?]π m²
Hint: Surface Area of a Cone = Tre + B
Where = slant height, and B = area of the base
Enter

Answer 1

264

Explanation:

The area of the base is
`\pi(8)^2=64\pi`.

So, the surface area is
`\pi(8)(25)+64\pi=264\pi`
