Question

Find the surface area of the cone. Round your answer to the nearest hundredth

Answer 1

Basically you do

2 x 3.14 x 8 squared

= 401.92

Then you do

401.92 + 14 x 8

=513.93

Hope this helps :)

Answer 2

Answer:

The correct answer is option option B 606.32 yd²

Step-by-step explanation:

Points to remember

Surface area of cone = πrl + πr²

Where r is the base radius and l is the lateral edge

To find lateral edge

l =  √(r²+ h²) =  √8² + 14²  = 16.12

To find the surface area of given cone

Here r = 8 yd and l = 16.12 yd

Surface area =  πrl + π r² = π * 8 * 16.12  + π8²

  = 606.32 yd²
