Question

cylinder has height 35 cm and radius 14 cm. Find the ratio of the total surface area and curved surface area​

Answer 1

Answer:

A≈4310.27cm²

r Radius

14

cm

h Height

35

Answer 2

Answer:

7:5

Step-by-step explanation:

given :- A cylinder has height 35 and radius 14 cm.

now let us find ratio between tsa and csa.

formula for total surface area of cylinder (tsa) =

2πr(r+h)

formula for lateral surface area of cylinder=

2πrh

now ratio between tsa and csa = 2πr(r+h)/2πrh

=(r+h)/h

= (14+35)/35

=49/35

= 7×7/7×5

=7/5

thus, ratio is 7:5
