First, we need to determine the area covered by Karina and Perry
For Karina, there are 9 square boxes each of which has an area of 1 unit sq
So:


For Perry:
There are 18 square boxes, each of which has an area of 1 unit sq.

Comparing both areas, we can conclude that <em>Perry's claim is correct while Karina is incorrect</em>
Answer:
4.013 units
Step-by-step explanation:
We know that the volume of a cone is given by the following equation:
v = pi / 3 * r ^ 2 * h
we need to know the height, therefore we solve for h:
h = 3 * v / (pi * r ^ 2)
replacing v = 105 and r = 5
h = 3 * 105 / (3.14 * 5 ^ 2)
h = 4.013
Which means that the height measures 4.013 units
How many times do 15 minutes fit into one hour? 4 times: 4*15=60 mins.
So that means that 4 times per hour 10 flights appear, and in total 4*10=40 planes arrive over one hour!
