The radius of a circle is 8 feet. What is the circle's area? Use 3.14 for .
2 answers:
Answer:
200.96 ft²
Step-by-step explanation:
Step 1: <u>Define/formula</u>
To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.
Step 2: <u>Solve</u>
According to the word problem, the radius is 8.
From here, we plug the numbers into the formula.
Step 3: <u>Conclude</u>
Therefore, the area of this circle is 200.96 ft.²

Answer:
Step-by-step explanation:
Since we have an amount in the future of 750, we are going to use Future value formula; FV = PV (1+r)^t
where PV= Initial amount deposited
r= interest rate or discount rate
t = total duration of the investment
FV= 750
PV=500
r = 2.5% or 0.025 as a decimal
t = ?
Next, plug in the numbers into the formula;
750 = 500* (1+0.025)^t
divide both sides by 500;
750/500 = 1.025^t
Introduce <em>ln</em> on both sides
ln 1.5 = ln
ln 1.5 = t ln 1.025
0.4054651 = 0.0246926 t
Divide both sides by 0.0246926 to solve for t;
0.4054651/0.0246926 = t
t = 16.42
Therefore it will take 16.42 years
