50.27 yards
30 pi m
Circumference = pi*2.5 = 7.85 km
Circumference of the circle: 13*pi = 40.841 cm rounded up to 3 decimal places
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
30 pi m
A circle with a diameter of 11 inches has an area of 95.03 square inches.
Circumference = pi*2.5 = 7.85 km
Circumference of the circle: 13*pi = 40.841 cm rounded up to 3 decimal places
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
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.
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
Using 3.14 as Pi the area of circle is: 2461.76
7.00
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
1.27 units 8/pi = 2.5464 2.5464 / 2 (you divide by two because the 2.5464 is the diameter of the circle. two radius = one diameter) = 1.273 round. 1.27
The final answer depends on what measure is wanted to the nearest hundredth!
