It is: pi*352 = 3848.451 square km to 3 decimal places
A circle with a radius of 0.9 km has an area of 2.54 square km
Using 3.14 as Pi the area of circle is: 615.44
A circle with a radius of 1.8 km has a circumference of 11.31 km
radius = 48/2 = 24 km
C = 31.4 km
A circle with a radius of 0.9 km has an area of 2.54 square km
The circle's area is 22,698 km2
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.
Using 3.14 as Pi the area of circle is: 2807.1913999999997
Using 3.14 as Pi the area of circle is: 615.44
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
A circle with a radius of 1.8 km has a circumference of 11.31 km
A circle with a radius of 126 km has a circumference of 791.68 km.
Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)
radius = 48/2 = 24 km
The radius is 71,461 km
Then it will have a diameter of 16 km
