An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2. Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.
The diameter of any circle is twice its radius. Therefore: 2 times 1737.4 = 3474.8 km.
The circumference is equal to pidiameter, or 3.143km 9.42 or 9 km rounded to the nearest km
Circumference at equator : 24,901.55 miles. (40075.16 km) Circumference pole to pole : 24,859.82 miles (40008 km)
The perimeter of the sun would be calculated as the perimeter (circumference) of a circle which is derived by multiplying 'pi' (3.14) by the diameter. The Sun's diameter is 1.4 million kilometers. Therefore, the circumference of the sun is 3.14 multiplied by 1.4 million which is equal to 4.396 million km.
A circle with a radius of 1.8 km has a circumference of 11.31 km
Circumference of circle: 2*pi*13.1 = 82.30972752 km
The radius is 71,461 km
C = 31.4 km
The circumference of a circle with a radius of 1.5 km is: 9.425 km (C = r x 2 x Pi).
Approximately 1068.142
If 11.6 km is diameter, then 11.6 * pi = 36.4425 km circumference If 11.6 km is radius, then 11.6 * 2 * pi = 72.8850 km circumference
42 pi km ~ 131.946891
The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
The circumference of a circle with a diameter of 16 km is: 50.3 km
If C = 449,000 km then radius = 71,500 km
If the area is a circle and the radius of the circle is 21 miles, the distance around the circle (circumference) is 131.95 miles. The area of that circle is 1,385.4 square miles.
