bearing in mind that 5¼ is just 5.25 converted to decimal.
let's say the number is "x", thus "x" is the 100%.
12.6 is 5.25%, what is the 100%? namely "x"?
Answer:
The area of a circle with a diameter of 10 inches is 78.5 in².
Step-by-step explanation:
1. Know the formula for finding the area of a circle.
A = r²
2. Since you need the radius for finding area, you will need to divide 10 by 2 because the radius is half of the diameter.
10 ÷ 2 = 5
3. Add in your numbers to the formula.
A = (5)²
4. Simplify the equation. We can use 3.14 for pi.
A = 25
A = 78.5
So, the area of the circle is 78.5 in².
Answer:
$105,477.02
Step-by-step explanation:
To solve this problem, we need to use a modified version of the compound interest formula:
<em>A = total balance
</em>
<em>r = interest rate
</em>
<em>n = number of times compounded annually
</em>
<em>t = time
</em>
<em />
First, change 4% to its decimal form:
4% -> -> 0.04
Now, plug in the values:
The principal was $105,477.02
