Circumference = pi * 2 * r
C = 3.14 * 2 * 47 = 295.16
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
The circumference of a circle when the diameter is 30 is: 94.25
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.
The formula for the circumference of a circle is C = 2πr, where r is the radius. Substituting 8.1 for the radius, we get C = 2 * π * 8.1 ≈ 50.92. Therefore, the circumference of the circle is approximately 50.92.
The answer depends on where the other end of the line segment is. If it is on the circumference the segment is a radius. Otherwise, it is indeterminate.
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
A circle with a radius of 5 units has a circumference of 31.42 units.
37.69
43.98 units
r = 0.95
138.23
A circle with a radius of 4 units has a circumference of 25.13 units.
0.95 - 0.96 units
47.25
Circumf. divided by 2Pi = radius 244.92 / 2Pi = 38.98 radius (to nearest hundredth).
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
16.6 x pi = 52.15 to the nearest hundredth
