A piece of paper has a rectangle ABCD in which AB= 10 cm and BC = 22 cm , it was folded to form a right circular cylinder such that AB is cincident to DC . Find the volume of the resulted cylinder

Step-by-step explanation:

given data:

AB= 10 cm.

BC = 22 cm.

volume of a cylinder V =

h = 10.

solution

base of the circumference = 22cm

circumference of a circle =

r = radius is unknown.

.........................eq1

where insert this into eq1.

next we solve for the volume of the cylinder.

recall  

h = 10cm

r = 3.5cm

300pi

step-by-step explanation:

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
