360 degrees in a circle 120 degrees = 12mm 360 degrees = 36mm Therefore the circumference of the circle is 36mm.
Circumference = 2*pi*r Circumference = 2 *pi*12 mm 75 mm =====
1.2 cm in 12mm
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
To determine how much bigger 14mm is than 12mm, subtract 12mm from 14mm. This calculation shows that 14mm is 2mm bigger than 12mm.
No, 10mm is not thicker than 12mm. In fact, 12mm is thicker than 10mm by 2mm. Millimeters measure thickness, so a higher number indicates a greater thickness.
The circumference is 75.4mm
37.68 MM
circumference = 2*pi*12 = 75.398 mm to 3 decimal places
-- 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).
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
Circumference = 2*pi*r Circumference = 2 *pi*12 mm 75 mm =====
A = 452.4mm2
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.
d=2r, d=2x12mm=24mm
The radius is half of the diameter, and 1/2 of 24 is 12. The radius is 12mm.
