the equation is 2(pi)r so
2 (3.14) 3=
6.28*3=
18.84cm
About 18.85cm
circumference = 2pi4.2 = 26.389 cm to 3 decimal places
The circumference of a circle when the diameter is 30 is: 94.25
Circumference = 2*pi*radius (not raduis) = 19 cm, approx.
circumference = 2pi50 = 314.159 cm to 3 decimal places
Circumference = 2*pi*7.1 = 44.611 cm and rounded to 3 dp
The circumference of a circle if its radius is 3 is about 18.85
The radius of the circle is 9.772 cm rounded to 3 decimal place and the circumference of the circle is 2*pi*9.772 = 61.399 cm rounded to 3 decimal places
Circumference of circle: 2*pi*5 = 31.416 cm rounded to 3 decimal places
Well, isn't that a delightful question to ponder? To find the radius of a circle when you know the circumference, you can use the formula Circumference = 2 * π * radius. In this case, with a circumference of 28.6 cm, you can rearrange the formula to solve for the radius, which would be approximately 4.55 cm. Just imagine that perfect circle coming to life on your canvas!
A circle with a radius of 3 units has a circumference of 18.85 units.
circumference = 2*pi*8.6 = 54.035 cm to 3 decimal places
