Question

The curved area of a cylinder is 2π(y^2+7y+12) and it's radius is(y+3). Find the height of the cylinder​

Answer 1

Answer:

height = (y+4)

Step-by-step explanation:

radius (r) = (y+3)

height = h

curved surface area = 2π r h

2π ( y²+7y+12) = 2π r h

or y²+7y +12 =. r h

or y+ 3y+4y+12= rh

or y(y+3) + 4(y+4) = (y+3).h

or (y+3) (y+4) = (y+3) h

or h= y+4

Answer 2

Height = y+4
