A right cone has a radius of 13 cm and a slant height of 20 cm. Find its surface area. Question 12 options:

A)

10,618.6 cm2

B)

816.8 cm2

C)

1,347.7 cm2

D)

3,539.5 cm2

Step-by-step explanation:

Given that,

Radius of a cone, r = 13 cm

Slant height of the cone, l = 20 cm

We need to find the surface area of the cone. The formula for the surface area of the cone is given by :

Put all the values,

So, the surface area of the cone is .
