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 with a 1 cm radius?
C=2(pie)R i.e. C=2(3.141)1 C=6.282cm
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.
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)
A circle has 3.8 cm What is the radius?
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

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 radius of a 2 cm circle?

What is the circumference of a circle if the diameter is 1 cm?
The circumference of a circle if the diameter is 1 cm will be Pi (about 3.1416).
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
