C=pi times r2
The circumference of a circle can be found with this formula: Circumference = 2*(radius)*∏ where ∏ can be rounded to 3.14 Plugging in your radius of 4: Circumference = 2*4*∏ = 8*∏ which is around 25.13.
Well, darling, the circumference of a circle is calculated using the formula C = 2πr, where r is the radius. Plug in the radius of 4 mm, and you get a circumference of 8π mm, or approximately 25.13 mm. So, there you have it, sugar, the circumference of a circle with a radius of 4 mm.
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
A circle with a radius of 4 miles has a circumference of 25.13 miles.
8pi, the circumference is 2pi multiply by radius
The circumference of a circle can be found with this formula: Circumference = 2*(radius)*∏ where ∏ can be rounded to 3.14 Plugging in your radius of 4: Circumference = 2*4*∏ = 8*∏ which is around 25.13.
The formula for circumference of a circle is 2πr. Since the radius is 4, the circumference is 8π or approximately 25.12 inches.
The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle. In this case, if the radius is 4 inches, then the circumference would be C = 2 x π x 4 = 8π inches, or approximately 25.13 inches.

The circumference of a circle with a radius of four is: 25.13
Well, isn't that just a happy little question! To find the circumference of a circle, you can use the formula C = 2πr, where r is the radius of the circle. Since the diameter is twice the radius, if the circle has a diameter of 4 feet, the radius would be 2 feet. Plugging that into the formula, the circumference would be 4π feet.
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
A circle with a radius of 4 miles has a circumference of 25.13 miles.
circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
Circumference of a circle is measure with the formula: C = 2*pi*r where C is the Circumference, and r is the radius. Hence, the circumference of a circle with radius 4 m would be: C = 2*pi*4 = 8*pi Rounded to 2 decimal places, this comes to 25.13 m . Hope this Helps.
circumference=2 times (pi) times r: where r is the radiusC=2pir
2, because the radius is half of the circumference
