we know circumference=2*pi*r; where r=1; circumeference=2*3.14*1=6.28 cm
The circumference of a circle is C = 2πr, where C is circumference, π is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius
The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
we know circumference=2*pi*r; where r=1; circumeference=2*3.14*1=6.28 cm
circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) = 6.28 cm ÷ (2 x π) ≈ 1 cm
If the circumference of a circle is 65.98 cm the radius is about 10.5 cmThe formula C = pi (2r) means that r = 1/2 (C/pi)
Radius in from the center of circle or sphere, so a radius of 3.8 cm is a diameter of 7.6cm and circumference 23.8 cm (or 24 cm). Or If you mean 3.8 is the diameter (width), then radius is half (1/2) which equals 1.9 cm and circumference of 11.9 cm (12cm). Or If circumference 3.8 then radius is 1.2cm and area is 1.152cm. I hope this answers your question. lofty_720@yahoo.com.au
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
If a circle has a radius of 1, the diameter is 2, and the circumference is 6.28 (approximately).
A circle with a radius of 1 meter has a circumference of 6.28 meters.
The circumference of a circle is C = 2πr, where C is circumference, π is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm
The radius of a 2 cm circle is: 1 cm
The circumference of a circle if the diameter is 1 cm will be Pi (about 3.1416).
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
Circumference of the circle is: 2 times pi
