Step-by-step explanation:

we know that

The volume of a cylinder is equal to

where

r is the radius of the base of the cylinder

h is the height of the cylinder

In this problem we have

Remember that

the circumference of a circle is equal to

Solve for r

substitute

Find the volume

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
