-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
The area of a circle with a diameter of two cm is about 3.1416 cm.
The area of a circle if the diameter was s 7ft is 38.48ft
the diameter is the length across the circle, the area is pie r squared r is radius, which is half of the diameter
The area of a circle with a diameter of 10 centimeters is: 78.54 cm2
If the diameter is 12mm then the radius is 6mm. The area of a circle is pi X r2. Therefore pi X 36 mm2 = about 113.0973 mm2 = area of the circle. Don't forget units!! pi is about 3.1416.
12mm - half the diameter.
37.68 MM
Area of a circle = pi*r2 , where pi = 3.14 and r is the radius of the circle. We have diameter(d) = 12mm so, radius(r) = d/2 = 6mm On putting the values we get Area = 3.14*62 = 3.14*36 = 113mm2
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
A = 452.4mm2
d=2r, d=2x12mm=24mm
The radius is half of the diameter, and 1/2 of 24 is 12. The radius is 12mm.
The diameter of a circle with an area of 37.68 is 6.92
The area of a circle with the diameter of 3m is 7.069 m2
The area of a circle with diameter of 4.9 is 75.43 units2
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
