How do you find the circumference of a circle without knowing the radius and area?
You will have to measure some part of the circle. As long as you have absolutely no information about a circle, you can't do any calculations.
How do you find ratio of area to radius?
In a circle, the area of the circle is pi times the radius squared
How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
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 to find area of a circle?
you take the radius and multiply it by itself. then you multiply the radius squared by 3.14 to get the area of a circle...
How do you find the area of a circle by only knowing the radius?
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
How do you find the area of a semi circle knowing the radius?
count the number of sides?
Why it is so important to know the area of a circle?
Knowing the area of a circle which is pi times radius squared will help you to find other properties of the circle

What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
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 circle?
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
How to find area of a circle?
you take the radius and multiply it by itself. then you multiply the radius squared by 3.14 to get the area of a circle...
