It is 100 units.
area of full circle = 400 sq. ft. if area = pi * radius2 then radius = square root ( area / pi ) = 11.284 radius (approx). = 22.568 diameter (approx).
Area = 10*20 = 200 square units
== == The answer is 200. 200 x 200= 40000 the answer is 200. 200 x 200= 40000
a 60 by 40 yard would yeild an area of 2400 sq feet.
The area of a circle whose diameter is 200 meters is: 31,420 m2
7.76 acres, approx.7.76 acres, approx.7.76 acres, approx.7.76 acres, approx.
Using 3.14 as Pi the area of circle is: 31400.0
Using 3.14 as Pi the area of circle is: 31400.0
d = 28.3
Divide the diameter by 2 to get the radius. Then use the formula for the area of a circle: area = pi x radius2.
100. The radius is 1/2 of the diameter.
Its diameter will be: 2*100 = 200 miles
Area = pi times radius2 where radius = 200 feet therefore area = pi times 2002 Area = 125 663.7 feet2
Area = pi * radius2 628mm2 = 3.14 * radius2 dividing by pi (approximately 3.14) 200mm2 = radius2 Taking the square root of 200, 14.14mm is the radius. The diameter is twice the radius, so the diameter is 28.28mm.
It is 100 units.
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
