Answer:
Step-by-step explanation:
The formula for the area of a circle is : 
To work this out you would first have to work out the area of the circle. You can do this by multiplying pi by 8 squared, this gives you 201.06. This is because in order to calculate the volume you must calculate the area of one face of the shape.
The next step is to multiply 201.06 by 10, this gives you 2010.62.
1) Multiply pi by 8 squared.
2) Multiply 201.06 by 10.
A cylinder can be made from this net.

The distance covered by bicycle is 1.885 km.
What is distnace?
Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.
Given: A bicycle wheel with radius 30cm made 1000 revolutions.
We have to find the total distance covered by bicycle.
First to find the circumference of the bicycle wheel.
Circumference = 2πr
where, r is the radius.
Here r = 30.
So,
Circumference = 2 x π x 30 = 60π
Now to find the total distance,
D = circumference x number of revolutions.
D = 60π x 1000
D = 188,495.5592 cm
D = 188,495.5592 /1000 km
D = 1.88 km
Therefore, the distance covered by bicycle is, 1.885 km.
