The distance around a circular park is 2.50 km How many hectares does it contain?

∙ 11y ago
Circumference = 2 pi R = 2,500 meters
R = 2,500/2 pi
Area = pi R2 = pi (2500)2/4 pi2
1 hectare = (100 meters)2
Area = (25)2/4 pi = 49.736 hectares (rounded)

The distance around a circular garden is 157.1 ft What is the radius to the nearest tenth of a foot?
Distance around circle = 2*pi*r = 157.1 so r = 157.1/(2*pi) = 25.00 ft so, to the nearest tenth of a foot, 25.0 ft

How long is 400 meters walking?
It is almost exactly a quarter of a mile. Once around a typical track and field oval. The distance the relay runners go, 4 x 100 meters. 40 acres (16 hectares) is a 400 meters by 400 meters roughly.
What is the circular region of a circle?
the distance around a circular region is called circumference

What is the distance around the edge of a 2 dimensional shape known as?
The distance around a two dimensional shape is known as the perimeter of the shape. If the shape is circular, it may be refered to as a circumference.

It is the distance around an outside of a round 180 circular object
The definition Circular motion?
Circular motion is the movement of an object in a circular path around a fixed point. The object continuously changes its direction, but its distance from the fixed point remains constant. It is characterized by a centripetal force keeping the object in its circular path.
What is the distance around the circular table with measures 15m across?
distance or circumference = 15*pi = 47.124m rounded to 3 decimal places
A runner races 800 around a circular track what distance does he cover?
800 meters, or about .5 miles.
What is the distance covered when a cyclist rides halfway around a circular track with the radius of 140M?
The distance covered by the cyclist when riding halfway around a circular track with a radius of 140 meters is equal to the circumference of the circle, which is 2 * π * radius. Therefore, the distance covered would be 2 * π * 140 = 880 meters.
What is the distance around a circular track in meters if its diameter is 200 meter?
The circumference is obtained by multiplying the diameter by pi.
Why does the distance between the earth and moon change?
It varies, since the moons orbit around earth is not perfectly circular and central.
What is the perimeter distance of 2 hectares?
as little as about half a kilometer if the area is circular but approaching infinity if it is exceedingly long & thin in fact if you wrapped your 2 hectares around the globe in a continuous band which would incidentally have to average less than half a millimeter wide if at the equator then the 2 edges of this band could extend more than 92000 kilometers in total & would never actually end nor ever meet to produce a true geometric shape with a perimeter in the usual sense of these terms
