How to find the diameter of a circle when given the circumference?

Mathematics

andre [41]3 years ago

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.

The measures of two sides of a triangle are 15 and 16. between what two numbers must the measure of the third side fall?
QveST [7]
If it is a right triangle and you given me adjacent and opposite the formula is
{r}^{2}   =  {x}^{2}  +  {y}^{2}
third side = 21.93

if its not right triangle you need the angle to solve

(01.06) Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x)= 3x − 3 The function g
Damm [24]

Answer:

<h2>They both have the same slope</h2>

Step-by-step explanation:

The standard equation of a given line is expressed as y = mx+c where m is the slope and c is the intercept.

given the function f(x)= 3x − 3, comparing this equation with the standard format, we will have;

mx = 3x

Divide through by x

mx/x = 3x/x

m = 3

Hence the slope of the function f(x)= 3x − 3 is 3.

For a function g(x) passing through the points (0, 2) and (1, 5), to determine the slope, we will use the formula for calculating slope expressed as;

m = Δy/Δx = y₂-y₁/x₂-x₁

From the coordinates, x₁ = 0, y₁ = 2, x₂ = 1, y₂ = 5

m = 5-2/1-0

m = 3/1 = 3

Hence the slope of g(x) passing through the points (0, 2) and (1, 5) is also 3.

<em>This shows that both functions have the same slope.</em>

You have a balance of $4,500 on your credit card. The interest rate is 12% (1% per month). The late payment fee is $40. You miss
Montano1993 [528]
I started by figuring out how much interest you get in a month by multiplying 4500 by .01. This gave me $45 as in interest. Then I added the payment fee, $40. 40+45 is 85, so the answer should be d). However, I'm not 100% positive. Somebody verify please? :)
