r=200 ft
d= 400 ft
c= πd
= 3.14 x 400
c= 1256ft
a= πr²
r² = 40, 000.... (remember always do the indicies first because of B.I.D.M.A.S)
3.14 x 40, 000
AREA = 125, 600 ft²
:)
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)
Oh, dude, like, the area of a circle is π times the radius squared, right? So, if the diameter is 200 m, the radius is half of that, which is 100 m. Just plug that into the formula, and you get an area of 31,415.93 square meters. Easy peasy, lemon squeezy.
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.
A circle with an area of 200 acres has a diameter of: 3,331 feet.
