Question

the curved surface area of a cone is670cm2 and it's radius is 15cm thenthe total surface area is​

Answer 1

Answer:

Since the base of a cone is a circle,

we substitute 2πr for p and πr2 for B

∴where r is the radius of the base of the cylinder. ►So, the formula for the lateral surface area of a right cone is L. S. A=πrl ,

►where l is the slant height of the cone .
