Csc (pi/2) or the cosecant of (pi/2) can be obtained by using a calculator.

In terms of degrees, pi/2 is equivalent to 90 degrees. Cosecant is also the reciprocal of sine. Since sin 90 is equal to 1, obtaining the reciprocal of 1 should yield csc (pi/2). Since the reciprocal is simply equal to 1, then:

Answer:

12 cm = 21.62 miles

6 cm = 11.04 miles

Step-by-step explanation:

To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of $\frac{map}{real world}$ and simplify.

We know $\frac{map}{real world}=\frac{0.5in}{2.3 miles}$ . We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write $\frac{4.7in}{xmiles}$ and $\frac{2.4in}{xmiles}$
