The sum of the heights and the radius of a solid cylinder is 35cm and its total surface area is 3080cm³, find volume of the cylinder.​

Respuesta :

The volume of the right cylinder is approximately 12938.184 cubic centimeters.

What is the volume of the solid cylinder?

In this question we know the sum of the height and radius and the surface area of the right cylinder, whose formulae are presented below:

3080 = 2π · r² + 2π · r · h

3080 = 2π · r · (r + h)                     (1)

r + h = 35                                       (2)

By (2) in (1):

3080 = 2π · r · 35

3080 = 70π · r

r ≈ 14.006

And by (2):

h = 35 - r

h = 35 - 14.006

h = 20.994

And the volume of the right cylinder is equal to:

V = π · r² · h                                            (3)

V = π · (14.006 cm)² · (20.994 cm)

V ≈ 12938.184 cm³

The volume of the right cylinder is approximately 12938.184 cubic centimeters.
