The formula for the circumference of a circle, c=πd or c=2πr, can also be used to find the diameter or radius of a circle.
Let's look at an example.
A circle has a circumference of 20.72 m. What is its diameter?
First, write down the formula.
c=πd
Next, fill in the values that you know.
20.72 m=3.14 d
Then, divide both sides of the equation by 3.14
6.6=d
The answer is the diameter is 6.6 meters.
Answer:
you don't because its not relivant
Step-by-step explanation:
(a) <1 and <2 are mutually supplemental angles
(b) because of (a) m<1 + m<2 = 180 degrees
2 hr 15 min = 2

hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 =
126 miles
"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
Answer:
A function of f is continuous on its domain if it is Dirichlet function
