Question

A right cone has a radius of 5 cm and a slant height of 13 cm. Find its surface area. Question 3 options: A) 90 cm2 B) 282.7 cm2 C) 300 cm2 D) 942.5 cm2

Answer 1

B. 282.7 cm²

Step-by-step explanation:

A right cone has a surface area of 282.7 cm²

Answer 2

B) 282.7 cm^2

Step-by-step explanation:

Surface area of a cone is given by the formula ...

A = πr² +πrh . . . . . . . where r is the radius, and h is the slant height

A = πr(r +h)

For the given cone, the area is ...

A = π(5 cm)(5 cm + 13 cm) = 90π cm²

A = 282.7 cm² . . . . surface area of the cone
