Question

the ratio between the CSA and TSA of a right circular cylinder is 1:2 find the ratio between the height and the radius of cylinder​

Answer 1

Answer:

Given: CSA of cylinder: TSA of cylinder = 1:2

Ratio between curved surface area and total surface area of cylinder = 1: 2

2πrh/2πr(h+r) =1/2

= h/h+r = 1/2

⇒ 2h = h + r

⇒ h = r

hence ratio is 1:1

Answer 2

Answer:

Hello There,

This is your answer.

Step-by-step explanation:

TSA = 2 π r ( r + h)

CSA = 2 π r h

CSA / TSA = 2 π r h / 2 π r ( r + h)

⇒ ½ = h / ( r + h )

2h = r + h

h = r

⇒ h : r = 1 : 1

HOPE IT HELPS YOU!!!

HAVE A GREAT DAY AHEAD!!!
