Mathematics

Answer:

<u>417.4ft^2</u>

Step-by-step explanation:

Surface area of a cone = πr(r+√r²+h²)

r is the radius

h is the height

Substitute

Surface area of a cone = π(5)(5+√5²+21²)

Surface area of a cone = πr(5+√25+441)

Surface area of a cone = π(5)(5+21.59)

Surface area of a cone = 3.14*5*26.59

Surface area of a cone <u>= 417.4ft^2</u>

<u>Hence the surface area of the cone is 417.4ft^2</u>
