The perimeter of a circle is called the circumference
To find the circumference of a circle you do 2 times pi times radius
C = 2 * 3.14159 * 7 = 43.98inches
Since this is a half circle you have to take half of the circumference...
you answer is 21.99inches

How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
How do you find the perimeter of a circle with just the diameter?
the perimeter is 3 times as long as the diameter Example: if my diameter is 7 inches long my perimeter is 3 times as much so it is 21 inches long
How do you find the raduis of a circle knowinng only the circumference?
Radius = circumference/pi
What is the formula to find the circumference of a circle with the raduis given?
Circumference of a circle: 2 x pi x radius.
How do you find the perimeter if you already know the circumference of a circle?
The circumference of a circle is the length of the circle's perimeter.
How do you find the raduis of a circle if you know the density?
You cannot.A circle has no mass nor volume and so the concept of density is not appropriate.Also, the word is radius, not raduis!
Find the area of a circle whose radius is 2 inches?
To find the radius the formula is pi*radius*raduis So it is going to be 2 to the second power.......Leaving you with an answer of 4 inches......Be sure to include pi

Circumference of a circle: 2 x pi x radius.
What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
How do you find the perimeter if you already know the circumference of a circle?
The circumference of a circle is the length of the circle's perimeter.
How do you find the perimeter when circumference is given?
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
How do you find the circumference of a circle when the raduis is a fraction?
The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
What is the formula of a perimeter of a circle?
to find the perimeter of a circle you simply do this (pi x D )
To the nearest hundredth what is the radius of a circle with a circumference of 7?
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
