The total length around the circle = 2 pi r = 2*pi*16 = 32 pi
Total degrees around the circle = 360 so
length of the arc of measure 270 = 32 pi * 270/360 = 24 pi units
or 75.40 units to the nearest hundredth

A rectangular prism has a lot of volume. Volume is the amount of scpace the cereal can go.
Find the rate of change, (y2-y1)/(x2-x1), from the data given...
(2.16-1.26)/(12-7)=0.18
(1.26-0.72)/(7-4)=0.18
Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...
c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)
The answer is d)3 because each number gets multiplied by 3 to qual the next number
