A = pi(r) ^2
A = 3.14(5) ^2
A = 15.7 ^2
A = 246.49
Hope this helps.
Divide 2012 by 360: 5.588888....
This means "5 full revolutions" plus 0.5888... of a revolution."
(0.5888 ... )*(360 degrees) = 212 degrees (answer)
The amount needed such that when it comes time for retirement is $2,296,305. This problem solved using the future value of an annuity formula by calculating the sum of a series payment through a specific amount of time. The formula of the future value of an annuity is FV = C*(((1+i)^n - 1)/i), where FV is the future value, C is the payment for each period, n is the period of time, and i is the interest rate. The interest rate used in the calculation is 4.1%/12 and the period of time used in the calculation is 30*12 because the basis of the return is a monthly payment.
FV = $3,250*(((1+(4.1%/12)^(30*12)-1)/(4.1%/12))
