Find the area of each figure. A square inscribed in a circle with radius \(r\)
Use a calculator or the trigonometry table on page 311 to find the area of each figure to the nearest tenth. An isosceles triangle with a \(32^{\circ}\) vertex angle and a base of \(8 \mathrm{cm}\)
Complete the table. Leave answers in terms of \(\pi\). $$\begin{array}{|l|c|c|c|c|c|c|c|c|}\hline & 1 . & 2 . & 3 . & 4 . & 5 . & 6 . & 7 . & 8 . \\\\\hline \text { Radius } & 7 & 120 & \frac{5}{2} & 6 \sqrt{2} & ? & ? & ? & ? \\\\\hline \text { Circumference } & ? & ? & ? & ? & 20 \pi & 12 \pi & ? & ? \\\\\hline \text { Area } & ? & ? & ? & ? & ? & ? & 25 \pi & 50 \pi \\\\\hline\end{array}$$
The area of a rhombus is \(100 .\) Find the length of the two diagonals if one is twice as long as the other.
If a value of \(\pi\) is required in the following exercises, use \(\pi \approx 3.14\) a. At a subway stop, a train arrives every six minutes. waits one minute. and then leaves. If you arrive at a random time, what is the probability there will be a train waiting? b. If you arrive and there is no train waiting. what is the probability that you will wait no more than two minutes before one arrives?
