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
What is the area of a 9Cm diameter circle?
A circle with a radius of 4.5Cm has an area of 63.62Cm2
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 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.
Find diameter when you only have area of a circle?
pi*radius2 = area of a circle radius2 = area/pi radius = square root of (area/pi) diameter = 2*radius
