Question

The ratio of the total surface area to the volume of a cylinder whose radius is 10 cm and height 20 cm, is​

Answer 1

Answer:

solution

Step-by-step explanation:

Let the total surface area and lateral surface area are S

1

and S

2

respectively.

S

1

=2πr

2

+2πrh

and S

2

=2πrh

Thus,

S

2

S

1

=

2πrh

2πr(r+h)

=

h

r+h

=

60

20+60

=

60

80

=
