The circular base of a cone has a radius of 5 centimeters. the height of the cone is 12 centimeters, and the slant height is 13 centimeters. what is the approximate surface area of the cone? use 3.14 for π and round to the nearest whole number

Hence, the surface area of cone is:

282.6 cm^2 which is approx 283 cm^2.

Step-by-step explanation:

We are given:

           i.e. r=5 cm.

               i.e. h=12 cm.

                    i.e. l=13 cm.

Now we know that the surface area(S.A.) of cone is given by:

Hence by putting the value of l,r and π in the formula we get:

Hence the surface area of cone is 282.6 cm^2 which is approx 283 cm^2.
