X decreased by the square of nine
x - 9^2 = x - 81
Volume of a cylinder = pi r^2 h where r = radius of the base and h = the height.
so if we are given a radius of 2 cm and a volume of 180 cm^3 we work out the height as follows:-
180 = pi * 2^2 * h
h = 180 / (pi*2^2)
height h = 180 / 4pi = 14.32 cm to nearest hundredth
She had 4m marbles in the 4 bags
So number of marbles that Helena has = 4m + 3.
Answer:
