Answer:
The radius will be half of your diameter so,
since 26 is your diameter half of that is = 13 is your new radius.
Now finding the area:
13^2 = 169
169 x 3.14 = 530.66 cm2 is your area.
Formula of an area of a circle:
πr^2
pi(3.14 or 22/7 depending on whatever they tell you to use for pi) x radius being squared
A) it would be a ratio of 5:1, y=5x
B) if x is 12, it has doubled, so you do the same to y, so it would be 60
Friendly phone= 0.06×400=24; 0.25×400= 100; 100+24+3.95=127.95; 127.95×4= $511.8
Chatter= 0.098 × 400= 39.2; 0.192 × 400= 76.8; 76.8+39.2+4.95= 120.95; 120.95 × 4= $483.8
Phone A Lot= 0.089 × 400= 35.6; 0.24 × 400= 96; 35.6 + 96= 131.6;
131.6 × 4= $526.4
Chatter < Friendly phone < Phone A Lot
$483.8 < $511.8 < $526.4
The cheapest one would be Chatter= $483.8
Hope this helps :)
