Answer:
432π cm² or 1356.48 cm²
Step-by-step explanation:
The area of a circle is πr²
The area of the disks are 144π and 576π.
576π-144π = 432π
432π ≈ 1356.48 cm²
X+2,000=stocks
x=bonds
7.2%⇒(.072)(x)=bonds invested
6%⇒(.06)(x+2,000)=stocks invested
Here is the equation:
x(.072)=(.06)(x+2,000) | Since the income from both equal
You then solve each side first (assume you know how to but if not, let me know)
You first multily the parentheses/x variables
⇒.072x = .06x+2,000(.06)
⇒.072x = .06x+120
You then minus .06x from each side
⇒.012x = 120
You then divide each side by .012
.012x÷.012=x
120÷.012=10,000
x=10,000
Now change the original x variables with 10,000
.072($10,000)=$720 bond interest
<u>They are equal so $720×2=$1440</u>
since it is a square, all sides are 6. and the area would be 36 because 6x6 is 36! and the perimeter is 24! Hope this helps! :)
