Question

I want answers of question 11 plz fast

Answer 1

Answer:

Lateral Surface area of the cone = π x r x l (since we cannot include the bottom as it is part of the cylinder)

Lateral surface area of the cylinder = 2πrh (we must include the base) + πr^2.

Finding the total surface area = πrl + 2πrh +πr^2

πr ( r + l + h) sq cm.

Hope this helps

Answer 2

Answer:

surface area of the given figure = c.s.a of cylinder + csa of cone

= 2πrh + πrl

= πr(2 h + l)
