area = pi*radius2
Remember, to half the diameter to get the radius.Get the area of the outside circle, and the area of the inside circle, then take the inside area from the outside.
I think it would be more helpful to you not to give you the answer. Work it out from this. If you are wondering what pi is, it is 3.14159
The diameter of a circle with a circumference of 12 is: about 3.82To to this calculation for other circles, just divide the circumference by Pi (about 3.1416). The result is the diameter.
If you divide 600 mm by 37 mm, you will know how many circles you can place side-by-side. In other words, you would be comparing the diameters.If on the other hand you want to compare the area, you have to square the previous result.
Circle is a shape. We have gotten to know a lot from circles. Because of circles, we get PI, radius, diameter, circumference, and other things. Circles fall into geometry, which is math. We can make many mathematical equations from circles.
The circumference of a circle with a diameter of 30 centimeters is: about 94.25 cm. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).

The circumference of a 7 feet diameter circle is: about 21.99 feet.You can easily to this calculation for other circles by multiplying the diameter by Pi (about 3.1416). The result is the circle's diameter.
The circumference of a circle 8.75 inches diameter is: about 27.49 inches.You can easily do this calculation for other circles by simply multiplying the diameter by Pi (about 3.1416).
The circumference of a 5-inch circle is about: 15.71 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
If a circle has a circumference of 6 ft, the diameter is: about 1.91 feet. You can easily do this calculation for other circles by dividing the circumference by Pi (about 3.1416). The result is the diameter.
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
The circumference of a circle if its diameter is 8 inches is: about 25.13 inches.To do this calculation for other circles, just multiply the diameter by Pi (about 3.1416). The result is the circle's circumference.
The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
