Answer:
16 ft²
Step-by-step explanation:
Since we're told that 2 ft diameter was cut of the board. We use the formula for hollow circle to find the area.
Area of remaining body = area of full body - area of removed body.
Area = πd²/4
Area of remaining body = (π * 5²)/4 - (π * 2²)/4
Area of remaining body = 19.64 - 3.142
Area of remaining body = 16.49 ft²
Therefore, the remaining area is then calculated into 16 ft²
Total = Principal * (1 + (rate/n))^n*years
where n is the number of compounding periods per year
Total = 12,500 * (1 + (.0275/4) )^40
Total = 12,500 * <span>(1.006875) ^40
</span>Total =
<span>
<span>
<span>
12,500 * 1.3152923995
</span>
</span>
</span>
Total =
16,441.16
