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)
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
The formula to calculate the circumference of a circle is C = πd, where C is the circumference, π is approximately 3.14, and d is the diameter of the circle. If the diameter is 1 cm, then the circumference would be C = π(1) = 3.14 cm.
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 radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
Oh, dude, you're hitting me with some math here. So, the radius of a circle is half of its diameter, right? And since you're telling me the diameter is 3.8 cm, the radius would be half of that, which is 1.9 cm. Easy peasy, lemon squeezy!
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
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
