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.
If the radius of a circle is 4 inches what is the diameter circumference and area?
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
How do you figure out the circumference of a circle?
Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)
What is the circumference of a circle witha radius of 4 ft?
The circumference of a circle with a radius of 4 ft is: 25.13 feet (r x 2 x Pi = circumference).
How do you find the circumference of a circle with a radius of 4?
Circumference of a circle = 2*pi*radius = 8*pi or 25.13274123 units
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 the circumference of a circle when the radius is 4 inches?

What is the circumference of a circle with a diameter of 8inch's?
A circle with a radius of 4 inches has a circumference of 25.13 inches.
What is the circumference of a circle with a radius of 4in?
circumference = 2*pi*4 inches
What is the radius of a circle with circumference 8pi inches?
radius of a circle = 4 inchesCircumference of a circle = 2π radiusradius = circumference/ 2π= 8π/2π= 8/2= 4
What is the radius of a circle with circumference 8 pi inches?
radius of a circle = 4 inchesFormulas:Circumference of a circle = 2π radiusradius =circumference/2π=8π/2π=8/2= 4
If the radius of a circle is 4 inches what is the diameter circumference and area?
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
How do you find the circumference of a circle if you know the radius?
Multiply the radius by 2 to get the diameter. Then multiply the diameter by pi to get the circumference. Example: If radius = 2 inches, diameter = 4 inches circumference = 4 x pi = 4 (3.1416) or about 12.57 inches
32 A circle has a radius of 2 inches What is its circumference?
4*pi or 12.56
If a circle's circumference is 4pi inches and it's area is 4pi square inches what is the radius of the circle in inches?
Circumference is pi * r * 2. Area is pi * r2. In your circle, both r * 2 and r2 equal 4. Your radius is 2 inches.
