Diameter = 2 x radius = 9 meters
The radius of a circle is half of its diameter. If you are referring to a circle with a diameter of 90 meters, then the radius would be 45 meters. If 90 meters is already specified as the radius, then the radius is simply 90 meters.
90mm / 2 = 45 mm
A circle with a radius of 45 units has a circumference of 282.74 units.
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
Using 3.14 as Pi the area of circle is: 6358.500000000001
A 45-meter diameter is equivalent to a circle with a radius of 22.5 meters.
The radius of a circle is half of its diameter. If you are referring to a circle with a diameter of 90 meters, then the radius would be 45 meters. If 90 meters is already specified as the radius, then the radius is simply 90 meters.
32cm, the radius is half of the diameter
90mm / 2 = 45 mm
A 45-meter object has a diameter of 45 meters. The diameter is the distance across the widest point of a circle or sphere, equal to the specified length of 45 meters in this example.
The area (A) of a circle is A = π . r2 The diameter (D) is equal to D = r / 2 . Were r is the radius. If the diameter of the circle is 45 mm, and we divide it by 2. We will obtain the radius which is equal to 22,5mm: D = 45mm / 2 = 22,5mm If we square this radius the result is 506,25mm2: r2 = (22,5mm)2 = 506,25mm2 So the area of the circle of diameter 45mm is: A = 506,25mm2 . π = 1590,43mm2d
A circle with a radius of 45 units has a circumference of 282.74 units.
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
Radius is 45.
The radius of a coin with diameter of 45 mm is : 45/2 = 22.5mm The circumference of a coin with diameter of 45 mm is 45*pi = 141,372mm rounded to 3 decimal places
Using 3.14 as Pi the area of circle is: 6358.500000000001
