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)
Well, darling, if the circle has a diameter of 3.8 cm, then the radius would be half of that, which is 1.9 cm. It's as simple as cutting a cake in half, but without the calories. So, grab a ruler and measure that radius like the sassy math pro you are!
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
