Question

the volume and curved surface area of cylinder are 1650 cm cube and 660 CM square respectively find the radius and height of the cylinder ​

Answer 1

Answer:

Step-by-step explanation:

2*pie*r*h=660 (a)

Pie*r*r*h=1650 (b)

From a

2*22/7*r*h=660

r*h =(660*7)/2*22

r*h =105

r = 105/h (c)

By putting c in b we get

22/7*105/h*105/h*h=1650

h=(22*15*105)/1650

h=21cm

Hence height is 21 cm

Thus from a

We get

2*22/7*r*21=660

r= 660/2*22*3

r =5cm

Hence radius is 5 cm
