Answer:

200. 96 cm^2

Step-by-step explanation:

If the area of a circle is $\pi$ $r^{2}$

$\pi$ = 3.14,

radius = 8 cm (r = diameter/2 ----> r = 16/2)

= $\pi$ $r^{2}$

$= 3.14 (8^{2})\\= 200. 96 cm^{2}$

Part A: c for cost. c=0.31m+0.5

0.31m is the cost per minute. 0.5 is cost per call.

Part B: 0.31m+0.5=5.15 to solve we must rearrange.

subtract 0.5 from each side giving us 0.31m=4.85

divide by 0.31 giving us m=15.65
