Formula of the daily compound interest:
A = P.e^(r.t), where P is the initial investment, r = interest rate, t = number of years e= 2.718 and A = final amount
6,225.18= 4,543.11(e)^(r.15)
(e)^(r.15) = 6,225.18/4,543.11
(e)^(r.15) = 1.3702046
ln[(e)^(r.15)] = ln(1.3702046)
15.r = 0.314991
And r = 0.314491/15 = 0.020 OR 2%
Answer: the shaded region = 69.66mm^2
Explanation:
Assume shaded region is X
Then :
X + Area of circle = area of square
X = area of square - area of circle
Find area of square:
Side length = 18mm
Area = 18 x 18 = 324
Find area of circle:
Side length of a square = the diameter of the circle = 18mm
And r(radius) = d/2 = 18/2 = 9
Area = pi x 9^2 = 254.34
Now find X
X = 324 - 254.34 = 69.66
