(3/5)³
=(3³)/(5³)
=27/125
---------------
As:
3*3*3=27
And:
5*5*5=125
The men didn't pay $29 because they only payed $27.........$25 was for the room and $2 was for the tip to the bellhop
Explanation- The room was originally $30, but they got a $5 meaning they only payed $25 and then they payed the bellhop $2 which equals to $27
Volume of cone = (1/3)pi*r²h
56.52 = (1/3)*3.14*r²*6
56.52/(2*3.14) = r²
9 = r²
r² = 9
r = √9
r = 3
Diameter = 2*r = 2*3 = 6 inches. b.
