Area of Circle = 
They told us that for this circle, the area is 
If you put it back into the formula for area of a circle we get:
Area of Circle =
Divide both sides by 
.
144 =

Interest=1250-880=370
I=PRT
P=principal
r=rate in deicmal
t=time in years
1 month so t=1/12
P=880
I=370
370=880*r*1/12
370=220/3r
times both sides by 3
1110=220r
divdie both sides by 220
5.04545=r
505% interest
