Answer:
Phone 1 will allow Ellie to talk the longest
Step-by-step explanation:
Phone 1:
(0.10x) + 6 = y
(0.10x) + 6 - 6 = 22 - 6
0.10/0.10x = 16/0.10
x = <u>160</u> minutes
Phone 2:
(0.25x) + 5 = y
(0.25x) + 5 - 5 = 22 - 5
0.25/0.25x = 17/0.25
x = <u>68</u> minutes
The formula for the circumference is C = d*pi, so the diameter for the circumference 65 pi is 65.
To find the area in terms of pi, multiply the radius by the radius.
32.5 * 32.5 = 1056.25
The answer would be 1056.25 pi.
