Answer:
Radius is <u>2.8</u> Circumference is <u>17.584 or 17.6 Rounded to the nearest Tenths </u>
Step-by-step explanation:
1. Find circumference with the Formula <u>C=πd</u>
C=3.14 x 5.6
<u><em>C=17.584 or 17.6 Rounded to the nearest Tenths </em></u>
2. Radius is Always half of the Diameter.
5.6/2 = 2.8
<em><u>2.8 is your radius.</u></em>
3. If you want to check you work try the formula C=2πr to see if things checks out.
C=2 x 3.14 x 2.8
<u><em>C= 17.584 or 17.6 Rounded to the nearest Tenths </em></u>

19.2
To find the hypotenuse the equation would be: a^2 + b^2 = c^2.
12 squared is 144 and 15 squared is 225. Add them and you get 369. Then, square root 369 to isolate c. It'd be about 19.2

Answer:
$10,000
Step-by-step explanation:
You can define a variable that represents the answer to the question: the amount invested at 3.5%. Let's say that is x. Then the amount invested at 5% is 16000-x, and the total interest earned is ...
0.035·x + 0.05·(16000 -x) = 650
-0.015x +800 = 650 . . . . . . . . . . . . simplify
-0.015x = -150 . . . . . . . . . . . . . . . . . subtract 800
x = 10,000 . . . . . . . . . . . . . . . . . . . . divide by -0.015
The amount that should be invested at 3.5% is $10,000.
