Question

Find the surface area of the cone. Use 3.14 to approximate pi. Round your answer to the nearest hundredth.

Answer 1

surface area of cone =

$\pi \: r(l + r)$

where r is radius and l is slant height

r = 3 yd

l = 10 yd

Surface area =

$\pi \times 3 \: (10 + 3) \\ = 3.14 \times 3 \times 13 \\ = 122.46 \: {yd}^{2}$

Answer 2

Answer:

122.46
