Answer:
Circumference = 2 * radius * 3.14
82.14 = 2*3.14 r
r= 82.14/6.28=13.079 cm.
So the area = 3.14 r^2
3.14*13.079^2
537.129 cm ^2

X=number of months
how much is deducted total=number of months times amount deducted per m onth
amount deducted per month=45
number of months=x
how much deducted total=45x
460-deducted total is more than 100
460-45x>100
solve for x
add 45x to both sides
