What is the circumference of a circle with the radius if 4?
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.
To the nearest hundredth what is the circumference of a circle with a radius of 4?
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
What is the estimated circumference of a circle with a radius of 4 miles?
A circle with a radius of 4 miles has a circumference of 25.13 miles.
How do you find the diameter without the circumference?
The diameter of a circle can be found without the circumference using the formula d = 2r. This formula requires that you know the radius of the circle which is half of the diameter. To calculate the diameter you need to multiply the radius by 2. For example if the radius of the circle is 4 then the diameter would be 8 (4 x 2 = 8).You can also find the diameter of a circle if you know the circumference. To do this use the formula c = d. By rearranging the equation you can calculate the diameter as d = c/. For example if the circumference of the circle is 12.5 the diameter would be 4 (12.5/ = 4).
If the radius of a circle is 4 then what is the circumference?
8pi, the circumference is 2pi multiply by radius

What is the circumference of a circle when the radius is 4 inches?
The formula for circumference of a circle is 2πr. Since the radius is 4, the circumference is 8π or approximately 25.12 inches.
What is the circumference of a circle with the radius of 4?
The circumference of a circle with a radius of four is: 25.13
What is the circumference of a circle if the radius is 4 inches?
The circumference of a circle if the radius is 4 is about 25.13 units. (C = r x 2 x Pi)
What is circumference of a circle with a radius of 4 cm?
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 ;)

What is the circumference of a circle if the radius is 4 m?
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.
