Diameter = 2 x radius = 9 meters
radius: 4.5 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.
A 45-foot diameter circle has an area of 1,590.4 square feet.
0.45 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
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
Radius: 45/2 = 22.5mm
A 45-foot diameter circle has an area of 1,590.4 square feet.
