The formula is: circumference = 2 x pi x radius.
As always when you use a formula, plug in the values you know and solve for the ones you don't. So plug in 46 for the circumference and solve for the radius. (You'll get that the radius = (circumference)/(2pi)).
circumference = pi*46 cm
If the circumference of a circle is 12 cm the radius is: 1.91 cm
A circle with a radius of 0.5 cm has a circumference of 3.14 cm.
A circle with a radius of 7.7 cm has a circumference of 48.38 cm
A circle with a radius of 208 cm has a circumference of 1306.9 cm
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
circumference = pi*46 cm
The circumference of a circle if the radius is 5 cm is: 31.42 cm (radius x 2 x Pi = circumference).
The circumference of a circle with a radius of 8.5 cm is: 53.41 cm (radius x 2 x Pi = circumference).
A circle with a radius of 10 cm has a circumference of 62.83 cm.
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
A circle with a radius of 0.5 cm has a circumference of 3.14 cm.
A circle with a radius of 7.7 cm has a circumference of 48.38 cm
If the circumference of a circle is 12 cm the radius is: 1.91 cm
The circumference of a circle with an 8 cm radius is: 50.27 cm
A circle with a radius of 208 cm has a circumference of 1306.9 cm
A circle with a radius of 9.2 cm has a circumference of 57.81 cm
