The formula for the area of a circle is: A = pi r2 where r is the measure of the radius. If the diameter of a circle is 8 cm, then the radius is half of that measure or 4 cm. Plug that into the formula and use 3.14 to approximate pi.
A = 3.14(4)2
A = 3.14(16)
Area is approximately 50.24 square cm.

How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
If the area of a circle is given as 67cm squared find the diameter and then circumference of this circle?
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
What is the area of a circle where the diameter measures 450mm?
The formula to find the area of a circle is A = πr2, where A is area, π is pi (3.14159), and r is the radius. The radius is half the diameter, 1/2d or d/2. r = d/2 = 450mm/2 = 225mm A = πr2 = 3.14159 x (225mm)2 = 15904mm2
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)
Find the area of the sector when the sector measures 10 degrees and the diameter of the circle is 12?
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How to find the area of a circle?
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.

How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
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 an circle when the diameter is 10?
Area of the circle = pi*radius2 = pi*52
