Question

write the formula to find the lateral surface area of the cone​

Answer 1

Step-by-step explanation:

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 .

Answer 2

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 .

LATERAL HEIGHT OF THE CONE

Use the height of the cone and the radius of the base to form a right triangle. Then, use the Pythagorean theorem to find the slant height.
