What is the radius of a half circle when you have width and height?
If the half circle is on its flat side, the radius is its height. If the straight part of the half-circle is vertical, the radius is its width.
Half the diameter of a circle?
Half the diameter of a circle is called its radius.
Where can you find the radius?
Radius is half the length from one side of a circle to the other or half the diameter.
What is half of a diameter?
The diameter of a circle is twice the radius. A radius is half of a diameter.
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
If a circle has a radius of 12 meters what is the area half of the circle?
The area of any circle is (pi) x (radius)2 .The area of half the circle is just half of that number.
What happens to the area of a circle when the radius is cut in half?
the area of the original is 4 times the new value.
What happens to the radius of a circle when the diameter is reduced by half?
The radius is also reduced by half
Does the area of a circle treble if the diameter trebles?
No. The area of a circle is 3.142 x radius x radius (radius is half the diameter).
What is the area to a half circle that is 22 feet in diameter?
area of a circle is pi times radius squared. the radius is 11 feet. the area ofthe circle would be 380ft2 since it is a half circle you take half of 380... your answer is 190ft2
What happens to the circumference of a circle when its radius is cut in half?
It splits
What is the area of a semi circle with a radius of 3 inches?
It's half of the area of the whole circle...
How do you calculate the square footage of a half circle?
Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2
What is the formula for the area of a circle with a diameter?
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
What happens to the radius of a circle when the diameter triples?
The radius becomes one and a half times larger
Why do you find the area of a circle with pi times the radius squared?
You find the area of a circle with pi times radius squared because the radius is half the circle so to find the full area you need to multiply it again.
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
