Question

Write the formula to find the total surface area of the cone whose radius is 'r' units and slant height is 'l' units

Answer 1

Answer:

πr(r+l)

where r is radius

and l is slant height

Hope this helps...

pls, mark as brainliest...

Answer 2

The total surface area of cone of radius 'r' and slant height 'l' = πr^2 + πrl

= πr(r+l)
