Find the volume of a cylinder of height 10 cm if its base is a square of side 4 cm

Explanation:

The volume of the cylinder is given by the area of the base multiplied by the height.

In this case:

Height:

Base area = area of the square ()

the side of the square is:

thus, the area of the base:

Now we multiply this quantities, to find the volume:

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
