Question

Total surface area of a cylinder is 3080 cm and its
radius is 14 cm. Find its volume.​

Answer 1

Answer:

12939.47 cm

Step-by-step explanation:

A=2πrh+2πr2

V=πr2h

Solving forV

V=Ar

2﹣πr3=3080·14

2﹣π·143≈12939.46976cm³

Answer 2

Answer:

surface area of cylinder is given by 2πrh + 2πr^2,

=> 2πr(h+r) = 3080,

=> (h+14) = 3080/28π,

=> h+14 = 35.01 =35 ,

=> h = 21cm,

therefore,

volume of cylinder is πr^2h,

= π(14^2)(21),

= 12930 cm^3.
