Answer 1

What is the surface area of the cone? Use 3.14 for pi. (1 point) Responses 863.5 square centimeters 863.5 square centimeters 2,383.26 square centimeters 2,383.26 square centimeters 1,354.125 square centimeters 1,354.125 square centimeters 3,689.5 square centimeters
Slant line= 22 cm
Diameter= 25 cm

Answer 2

The surface area of a cone can be calculated using the formula:

A = πr(r + l)

Where r is the radius of the cone and l is the slant height.

Plugging in the given values:

A = 3.14(10)(10 + 15)
A = 3.14(10)(25)
A = 3.14(250)
A = 785 square inches

Therefore, the surface area of the cone is 785 square inches.
