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
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
32cm, the radius is half of the diameter
Circumference = diameter x pi, thus circumference/pi=diameter. Now all you have to do is plug in your numbers: 45cm/3.14= approx. 14.33 cm diameter
divide it by 3.141592653 then divide it by 2
The formula to find Circumference is: C = Pi x D (Pi is 3.1416 and D is Diameter). Hence, 3.1416 x 45 = 141.372 cm Square centimeters (sq cm) are a measure of area. Circumference is measured in linear centimeters not square centimeters. The answer is 141.372 cm.The circumference of a circle is Î *d.The circumference of a circle with a diameter of 45 centimeters would be 45Î cm.
divide the circumference (c) by pi (3.14) and then you have diameter. you will have to measure the radius by hand.
Radius: 45/2 = 22.5mm
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.
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
32cm, the radius is half of the diameter
141.372 Circumference equals pi times the diameter: 45 x 3.1416 = 141.372 If you memorize the formula, it will serve you well.
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
The idea is to multiply the diameter by pi.
approximately 141.3
