Answer 2

do you add the rh??

Answer 3

No, you multiply the radius and height.

Answer 4

im still not getting the answer im getting frusteraded

Answer 5

Whats the problem?

Answer 13

i guessed for that answer the correct answer was126pi idont get it!

Answer 14

is it 126pi?

Answer 15

I done it like that:-
\[2 \pi r(r+h)\]
\[2 \times 22 \div 7 \times 7(7+2)\]
=396.
I amn't getting the given question:(
