How do you find the bottom half of a circle?
To find the area of half a circle, use the formula for a circle pi*r^2 divided by 2. pi = 3.14, r = radius (half the distance across the circle)
How do you find the perimeter of a half circle?
Let r be the radius of the circle. Then the perimeter of the half circle is pi*r + 2r. That is half of the circumference plus the diameter.
How do you find the perimeter of a half circle with the raduis of 7 inches?
The perimeter of a circle is called the circumferenceTo find the circumference of a circle you do 2 times pi times radiusC = 2 * 3.14159 * 7 = 43.98inchesSince this is a half circle you have to take half of the circumference...you answer is 21.99inches
How do you find the center of a circle if you know the radius?
the radius is half of the diameter. and the middle of the circle is half way between this diameter.
How do you find half circle area in m2?
Area of half a circle in square m = pi*radius2 divided by 2
What does circumferince mean?
Circumference is the distance around a circle. It is found by multiplying the diameter by pi.
How do you find the bottom half of a circle?

How do you find the perimeter of a half circle?
Let r be the radius of the circle. Then the perimeter of the half circle is pi*r + 2r. That is half of the circumference plus the diameter.
How do you find the radius in a circle?
The radius of a circle is half the diameter or half the circumference divided by pi (3.1416).
What is the formula to find a radius of a half circle?
same as for a whole circle
How do you find the radius of a circle when you have the diameter?
Half it.

How do you find half circle area in m2?
Area of half a circle in square m = pi*radius2 divided by 2
If you had two and one third what do you do to find the radius of a circle?
you have find half
How do you find the radius of a circle inside a square?
The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.
How do you find out the radius of a circle?
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
