Question

write the formula to find the total surface are of the cone. whose radius r units and slant height is l units​

Answer 1

Answer:

T.S.A Of Cone = $\pi r^{2} + \pi rl$

Answer 2

Answer

TSA of cone = πr2 + πrl = πr(l+r) square units.

Step-by-step explanation:

How to calculate the total surface area of a cone? The total surface area of a cone is the combination of the curved surface as well as the base area of a cone. The formula to calculate the total surface area of the cone is: TSA of cone = πr2 + πrl = πr(l+r) square units
