Answer 1

it is number 3 on the attached file

Answer 2

is that 3sin(theta)?

Answer 3

i mean 3 sin (y)

Answer 4

I get this -(9/2)*Pi*(cos(Pi)*sin(Pi)-Pi)

Answer 5

intigrate pi*(3*sin(y))^2 from 0 to pi with respect to y

Answer 6

44.4132198

Answer 7

thank you!!!

Answer 8

is it right?

Answer 9

actually its 6pi squared

Answer 10

grr it is of by 14
