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
shepuryov [24]

Answer:

Hence, the surface area of cone is:

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

Step-by-step explanation:

We are given:

  • The circular base of a cone has a radius of 5 centimeters.

           i.e. r=5 cm.

  • The height of the cone is 12 centimeters

               i.e. h=12 cm.

  • The slant height is 13 centimeters.

                    i.e. l=13 cm.

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

S.A.=\pi r(l+r)

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

S.A.=3.14\times 5\times (13+5)\\\\S.A.=15.7\times 18\\\\S.A.=282.6

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