Problem:
An old coin is kept in a cubic box in such a way that the outline of the coin touches the 4 walls of the box, if the base of the box has a 24 cm perimeter, what is the area of the coin?

28.27 cm^2 (2 decimal places)

Step-by-step explanation:

side of box = 24/4 = 6

diameter of coin would be 6 too

area of coin = pi x (6/2)^2 = 28.2743

the solution is 12x-6y

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.
