Ok so we know that the distance around the circle (or circumference) is equal to the diameter times pi.
This means that
d being the diameter,
This means that:
= 12.00028271
= 12 m
So the diameter of the circle is 12 metres.
Hope this helped
The polar equation will be 
<h3> What is the polar equation?</h3>
A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.
From the equation, we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally, the polar equation for e = 1 and y = + c is mathematically represented as
Therefore the polar equation will be

Answer:
.....................
Step-by-step explanation:
5π rad/sec= 60 x 2.5 = 150 rpm. The bicycle travels 27π inches per revolution
<span>150 rpm = 150 x 27π in/min = (150 x 27π x 60)/(5280 x 12) = 12.05 mph </span>
There are 8 total numbers. Of those 8 numbers, 6 are odd. So, the probability of picking an odd number is 6/8 = 3/4 = 0.75.
Hope this helps!! :)
