The measure of the angle that represents
of a circle is 45°
Step-by-step explanation:
Let us revise some important rules in a circle of radius r
- The length of the circle is 2πr
- The measure of the circle is 360°
∵ An angle represent
of a circle
∵ The measure of the circle is 360°
- The measure of the angle is
of the measure of the circle
∴ The measure of the angle =
× 360°
∴ The measure of the angle = 45°
The measure of the angle that represents
of a circle is 45°

Using proportions, considering the relation between the height and the shadow, it is found that the cell phone tower is 50 feet.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
When the shadow is of 8 feet, the height is of 10 feet. What is the height when the shadow is of 40 feet? The<em> rule of three</em> is:
8 feet - 10 feet
40 feet - h feet
Applying cross multiplication:
8h = 10 x 40
Simplifying by 8:
h = 10 x 5 = 50 feet.

Answer: 30 mph is the answer.
Step-by-step explanation:
s = 3 miles
t = 6 minutes
so,
60 minute = 1 hour
1 minute = 1/60 hour
6 minutes = 1/60 * 6 = 0.1 hour
so
average speed = s/t
= 3/0.1 = 30 mph
