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

answer: do we write it

step-by-step explanation:

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
