The area of a cirle is:
PI * r2
Where "r" is the radius, and PI is approximately 3.14.
Hint: A radius is half of the diameter.

How do you find the radius and diamiter of a circle if the area is givin?
Since: area = pi * radius2 Then: Radius = square root ( area / pi ) And: Diameter = radius * 2
What is the diamiter of a circle with a radius of 8cm?
16 cm
If the diamiter is 5.5 what is the circumference?
Circumference of circle: 5.5 times pi
How do you find the circumference if a circle if you have the diamiter?
Multiply the diameter by 3.14 (pi).
Is a radious half the diamiter of a circle?
yes the radius is half the diameter. It goes from the edge of the circle to the centre.
What is the area of a circle with a diamiter of 3cm?
Using 3.14 as Pi the area of circle is: 0
What is the equation for the diamiter of a circle?
Diameter = 1/2 of the circle's radius. Diameter = 2 times the square root of (the circle's area/pi) Diameter = the circle's circumference/pi
How do you find the radius of a circle if you don't have the area?
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
What has a diamiter of 10?
A circle with a radius of 5.
How do you get diamiter?
The diameter of a circle is twice its radius.
How do you find the radius and diamiter of a circle if the area is givin?
Since: area = pi * radius2 Then: Radius = square root ( area / pi ) And: Diameter = radius * 2
What is the diamiter of a circle with a radius of 8cm?
16 cm
What is the area of a circle with radius of 46 cm?
6647.61cm2
If the diamiter is 5.5 what is the circumference?
Circumference of circle: 5.5 times pi
How do you find the circumference if a circle if you have the diamiter?
Multiply the diameter by 3.14 (pi).
Is a radious half the diamiter of a circle?
yes the radius is half the diameter. It goes from the edge of the circle to the centre.
How do you work out the area of a circle?
Area of a circle = pi*radius2 measured out in square unitsfor pi use this number 3.14159and remember the radius of a circle = half the diameter.----------------------------------------------------------------Thus a circle with a 10 inch diameter would have an area of:Radius = diamiter/2, which is 10/2= 53.14159 * (5*5) = 78.53975 square inches
