The circumference of a circle, if the radius is 11cm, is about 69.12cm
A circle with a radius of 8 units has a circumference of 50.3 units.
A circle with a diameter of 8 inches has a radius (not raduis) of 4 inches.
Diameter- 128 / pi = 40.7436654 or 41 feet, I had this on my homework, do you know how to show the work though? Tricky.
Well, isn't that just a happy little question! To find the diameter of a circle, you can use the formula: diameter = circumference / π. So, for a circle with a 128ft circumference, the diameter would be 128 / π ≈ 40.77 feet. Just imagine that circle as a lovely little friend, perfectly round and ready to bring joy to your day!
The circumference of a circle, if the radius is 11cm, is about 69.12cm
A radius (not raduis) of 15 units implies a circumference of 94 units.
Circumference = 2*pi*radius (not raduis) = 19 cm, approx.
A circle with a radius of 8 units has a circumference of 50.3 units.
C = about 12.57
Divide the circumference by 2pi
Radius = circumference/pi
Circumference of a circle = 2*pi*radius
Circumference of a circle: 2 x pi x radius.
circumference = 2*pi*9 inches
The circumference of a 128-foot diameter circle is: 402.12 feet.
The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
