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:
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.
