the sq. footage of the circle would be 3.14(radius squared). if the diameter is 200ft, then the radius is 100ft. So, 3.14(100x100)= 3.14(10,000)= 31,400 sq. feet
100. The radius is 1/2 of the diameter.
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.
acre = 43,560 square feet = 4,840 square yardsArea of a circle = (pi)·(radius)2 = (pi)·(200)2 = 125,663.7 square yards = 25.964 acres (rounded)
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
the sq. footage of the circle would be 3.14(radius squared). if the diameter is 200ft, then the radius is 100ft. So, 3.14(100x100)= 3.14(10,000)= 31,400 sq. feet
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).
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.
Area = pi times radius2 where radius = 200 feet therefore area = pi times 2002 Area = 125 663.7 feet2
It is 100 units.
