This is a matter of calculating the area of the two circles = πr2 In these cases the r = (1) 100 cm and (2) 150cm. Then you subtract the smaller area from the larger area.
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
The circumference of circle with a diameter of 23 meters is about 72.26 meters. (d x Pi = c)
Diameter of the circle: 2 times 1 = 2 meters
25.13 meters
3 meters, 1/2 of the diameter
Circumference = (diameter) x (pi)2 pi = 6.2832 meters (rounded)
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
The circumference of a circle with a diameter of 13.4 meters is: 42.1 meters (diameter x Pi = circumference).
A circle 3.83 meters in diameter has an area of 11.5 square meters.
A circle with a diameter of 18 meters has an area of 254 square meters.
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
The circumference (full circle) is the diameter multiplied by pi. For the "half-circle", you would have to divide that by 2.
It varies. There is no set diameter of a circle.
If the diameter of a circle is 37.3 meters its area is: 1,093 m2
a circle having a diameter of 1.4732 meters has an area of about 1.7 square meters.
The diameter of a circle with a 3-meter circumference is: 0.9549 meters.
What is the circumference of a circle with a diameter that is 8 meters? The circumference of a circle is C = diameter d times pi. pi = 3.14159 ... Circumference C = 25.133 meters.
