How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
If area of circle is 100pi what is the diameter?
If area of circle is equaled to 100pi what is the radius?
How do you figure out the diameter of a circle?
Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.
What is the area of a circle with the diameter of 26 using pi?
Using 3.14 as Pi the area of circle is: 530.66
How do you find the diameter if you have the area of a circle?
Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.
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).
How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
How do you work out the area of a circle with only the diameter?
By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
What is the radius and diameter of circle area 530.66cm2?
Radius = about 13cm Diameter = about 26cm
If area of circle is 100pi what is the diameter?
If area of circle is equaled to 100pi what is the radius?
What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
Do you need a diameter or a radius for the area of a circle?
Yes because the area of a circle is pi*radius squared
A circle of a radius has 15find the diameter and area?
diameter is 15 area of the circle is... 706.5 if im not mistaken
What is the diameter and area of a circle?
the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
What is the are of a circle if the diameter is 32 in?
The area of any circle is (pi) x (radius)2 .The radius is 1/2 of the diameter.
What is the area of a 9Cm diameter circle?
A circle with a radius of 4.5Cm has an area of 63.62Cm2
