A circle with a radius of 45 units has a circumference of 282.74 units.
The idea is to multiply the diameter by pi.
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
A 45-foot circumference circle has an area of: 161.1 square feet.
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
A circle with a radius of 45 units has a circumference of 282.74 units.
Radius is 45.
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
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.
The idea is to multiply the diameter by pi.
It is: pi times 45 = 141.372 cm rounded to three decimal places
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.
circumference = 2*pi*radius r = c/2*pi r = 6.28/2*pi r = 0.9994930426 units area of the circle = pi*r2 = 3.138408154 square units
A 45-foot circumference circle has an area of: 161.1 square feet.
45 inches are 114.3 centimeters or 1.143 meters. Scroll down to related links and look at "Comparison of centimeters and inches".
divide the circumference (c) by pi (3.14) and then you have diameter. you will have to measure the radius by hand.
