Unit 11: Volume and Surface Area Homework 1: Area of Plane Figures- Find Area.

Mathematics
1 answer:
uysha [10]2 years ago
5 0

Answer:

4. 432 cm^2/2 = 216 cm^2

6. 309.76 mm^2

8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2

484/2 = 242pi or 759.88 in^2.

10. 297.84 in^2/2 = 148.92 in^2

Step-by-step explanation:

To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.

A square is equal on all sides, so you would just square the measurement of the one side.

To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).

I hope this helps!

Amanda [17]
So.. in this case, the starting amount is the 500mg sample... and the rate of decay, negative rate, is 1%, and at the time, the elapsed days is 0, to t = 0, P = 400

\bf \qquad \textit{Amount for Exponential change}\\\\&#10;A=P(1\pm r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{starting amount}\to &500\\&#10;r=rate\to 1\%\to \frac{1}{100}\to &0.01\\&#10;t=\textit{elapsed period}\to &300\\&#10;\end{cases}&#10;\\\\\\&#10;A=500(1-0.01)^{300}
