Answer:
The amount we have to deposit in a savings account x = $ 17777.78
Step-by-step explanation:
Amount = $ 20000
R = 2.5 %
Time = 5 years
Take principal amount = x
Simple interest earned in five years
S.I. = 
------- (1)
We know hat total amount is given by
Total amount = principal amount + simple interest
A = x + S.I.
Given that the total amount after 5 years is = $ 20000
x = $ 17777.78
This is the amount we have to deposit in a savings account.
3.72÷1.5=2.48
$2.48 per pound
Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².
π≈3.14
A. C=πd
Simply plug in the numbers into the formula.
Diameter=Radius*2
17*2=34
C=34(π)
B. (π)(5²)
Plug in the numbers into the formula. Remember that half of the diameter is the radius.
C. (π)(4.5)
There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.
The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.
D. (π)(6.5²)
Remember that the formula for calculating the area of a circle is πr².
Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.
(π)(6.5²)
Therefore, the last answer choice is the correct answer.
