Question

the sum 9f the radius of the base and the height of a solid cylinder is 37m . if the total surface area of the cylinder is 1628cm2 . find its volume ​

Answer 1

Answer:

Step-by-step explanation:

Let radius of the cylinder= r m

Height = h m

Given (r+h)=37m

Total surface area= 2*pi*r(r+h)=1628

2*22/7* r*37=1628

r=(1628*7)/(2×22×37)

After cancellation

r=7 m

r+h =37

7+h=37

h=30m

i) csa of the cylinder=2*pi*r*h

=2*22/7*7*30

=1320 m^2

Voume =pi*r^2*h

=22/7*7*7*30

=4620m^3
