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 the area of a circle using its diameter?
The area of a circle is pi(radius)2 Radius is half the diameter. Simply divide the diameter in half and enter it into the equation 3.14(diameter/2)2
What is the radius of 13cm?
tell what the diameter (d) and radius(r) of each circle is by using this information
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
Diameter of a circle?
If you know the radiusGiven the radius of a circle, the diameter can be calculated using the formula:The Diameter is Twice the Radius, or D = 2RWhere R is the Radius.If you know the circumferenceIf you know the circumference of a circle, the diameter is found using the formula D= C/πwhere:C is the circumference of the circleπ is Pi, approximately 3.142
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)
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 area of a circle using its diameter?
The area of a circle is pi(radius)2 Radius is half the diameter. Simply divide the diameter in half and enter it into the equation 3.14(diameter/2)2

How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
Diameter of a circle?
If you know the radiusGiven the radius of a circle, the diameter can be calculated using the formula:The Diameter is Twice the Radius, or D = 2RWhere R is the Radius.If you know the circumferenceIf you know the circumference of a circle, the diameter is found using the formula D= C/πwhere:C is the circumference of the circleπ is Pi, approximately 3.142
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
'How do you find the radius of a circle?
If you have the circumference- You have to divide the circumference by 2*Pi If you know the diameter the radius is simply half the diameter. If you know the area of a circle, the radius can be found using the formula : R = √A/π where: A is the area of the circle and π is Pi, approximately 3.142.
How to calculate diameter using circumference and radius?
well if the radius is given then the diameter is : d=2r. as for in a circle the diameter is : d=2(pi)r pi=3.14
What is the area of a circle with a diameter of 5.6?
the area of a circle found using pi r square. the radius is half the diameter therefore the radius is 2.8 = 22/7x 2.8^2=24.64
One cent is equal to how many square feet?
You need to measure the diameter of the cent. Then divide the diameter in half to get the radius. The formula for area of a circle = ?r2, where ? is 3.14159. I think you would be better off using millimeters or centimeters instead of ft.
