Question

What is the surface area of the cone? Use 3.14 for π and round to the nearest hundredth.

About 5.23 square centimeters

About 18.84 square centimeters


About 75.36 square centimeters


About 37.68 square centimeters

Answer 1

About 18.84 square centimetres

Explanation:

The surface area of a cone is A=πr²+πrs

Since d=2cm, r=1cm because d=2r

Now we have everything we need to solve:

A=π×1²+π×1×5

A=π+5π=6π

A=6×3.14=18.84cm²

Hope this helps!
