Question

The curved surface of a cylinder is 2pie (6^2-7root3y -15) and it’s radius is (2y + 3). Find the height of the cylinder. (C.S.S of cylinder = 2pie r h)

What a confusing question! Please help (asap)

Answer 1

Answer:

the Karur surface of circle is to buy 652 - 731 - 15 and it is 2 y + 3 find the length of the lens is the correct answer is 650 2.7 3552 y + 3 thank you

Step-by-step explanation:

I hope this answer you have beneficial so like a star and released answer

Answer 2

Answer:

given CSA of cylinder =2π(y^2 −7y+12)

radius =y−3

we know CSA =2πrh=2π(y^2 −7y+12)

h= y−3 y^2r −7y+12

height = [see image]

Hence height of given cylinder is y−4
