Question

the ratio of TSA and CSA of a cylinder is 2:1, if the TSA is 616cm² find the radius and height of cylinder. ​

Answer 1

Answer:

Radius= 7 cm height= 7cm

Step-by-step explanation:

CSA /TSA= 1/2

2πrh/2πr(h+r)= 1/2

h/h+r =1/2

2h= r+h

2h-h= r

h=r

TSA=2πr(h+r)

616=2 x 22/7 x r (2r)

616x7/88= r square

49= r square

√49= r

7 = r

r= 7 cm

Radius = Height

7 cm = 7 cm

Answer 2

radius,r = 7

and

height, h = 7
