If the radius of a circle is 1 cm what is the circumference of the circle?
we know circumference=2*pi*r; where r=1; circumeference=2*3.14*1=6.28 cm
What is the circumference of a circle with radius 12cm in fraction?
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
How is pi in relation to a circle?
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).
If the circumference of a circle doubles the radius?
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
How do you find the radius of a circle if the central angle is 36 degrees and the arc length of the sector is 2 pi cm?
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.
If the radius of a circle is 1 cm what is the circumference of the circle?
we know circumference=2*pi*r; where r=1; circumeference=2*3.14*1=6.28 cm
What is the radius of a circle whose circumference is 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 what is the radius?
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)
Find the ratio of the circumference of 4Cm?
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
What is the circumference of a circle if the diameter is 1 cm?
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.
What is the circumference of a circle with a radius 1?
If a circle has a radius of 1, the diameter is 2, and the circumference is 6.28 (approximately).
What is the circumference of a circle with a radius of 1meter?
A circle with a radius of 1 meter has a circumference of 6.28 meters.
What is the radius of a 2 cm circle?
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.
What is the circumference of a circle with radius 12cm in fraction?
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
What is the circumference of a circle to give 1 meter square?
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
What is the circumference of the following circle with a radius of 1?
Circumference of the circle is: 2 times pi
If the circumference of a circle is 37.68 cm then what would be the radius?
(1/2 (37.68/pi)) _____________________________________________________ The relationship of the circumference to the diameter is π (pi) The formula is... C = π D To make this more useful when you already have the circumference and want to find the diameter... D = C / π So, in this case, assuming a value of π to be 3.142 and giving an answer to the nearest two decimal places... D = 37.68 cm / 3.142 = 12.00 cm As the radius is half the diameter, the answer is 6 cm.
