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 t
hat AB is cincident to DC . Find the volume of the resulted cylinder
1 answer:
Answer:
Step-by-step explanation:
given data:
AB= 10 cm.
BC = 22 cm.
volume of a cylinder V =
h = 10.
<em><u>solution</u></em>
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

It’s 60.
A line has 180 degrees, if one half of the line has 120 degrees, then 180-120 = 60.
Add 5 to both sides of this inequality <span>x - 5 > -2: x > 3 (answer)</span>
There are 8 equal parts. Each part is 1/8 of the whole 8/8
2 x 18 = 36
5 x 18 = 90
36 + 90 = 126
