Then

We know that

If BC is the diameter of the circumference then the radius R is:



Now we convert the anglo from degrees to radians
Finally


Answer:

B) 32.0625 square cm.
Step-by-step explanation:
<u>Perimeter:</u> Just add all the sides together like so:
4.75x2 + 6.75x2 = 23cm.
<u>Area:</u> Multiply the base and height together:
4.75 x 6.75 = 32.0625 square cm.

Answer:
A) Enterprise: E(x) = 50 +0.25x; Hertz: H(x) = 30 +0.45x
B) see attached graph
Step-by-step explanation:
A) We choose to compare Hertz (lowest daily charge) and Enterprise (lowest mileage charge). In each case, the total charge will be the sum of the daily charge and the product of the mileage charge and number of miles (x).
Enterprise: E(x) = 50 +0.25x
Hertz: H(x) = 30 +0.45x
