12mm - half the diameter.
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
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
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
A = Pi x R² (Pi = 3.1416, R² = 1/2 diameter multiplied by itself) 3.1416 x 36 113.0976 sq mm
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)
