Area = Pi*r*r
3.14*20*20=1256 about
C=2*pi*r
2*3.14*20=125.6 about

How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find the circumference if you have the area of a circle?
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
How do you find the circumference of a circle when you have the area of a circle?
you divide the area by pi. then, find the square root of the number you have. now you have the radius. find the circumference by multiplying by the diameter or by multiplying by two times the radius.
How can you use a segment in a circle?
if it is the radius you can find area or circumference
How do you find the circumference of a circle with the area given?
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
What is the circumference and area of a circle that has a radius of 4?
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
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 circumference and area of a circle if radius is known?
Circumference = 2*pi*radius Area = pi*radius2
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 circumference of a circle when you have the area of a circle?
you divide the area by pi. then, find the square root of the number you have. now you have the radius. find the circumference by multiplying by the diameter or by multiplying by two times the radius.

How do find the circumference and area of a circle?
2 x pi x radius = circumference pi x radius squared = area
How do you find the circumference of a circle with the area given?
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
What is the area of a circle in terms of its circumference?
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
