The area of the circle is 490.87 cm2
it's 25 sq in
50 cm is the diameter.
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
78.54 yards
The area of the circle is 490.87 cm2
A circle with a diameter of 25 mm has an area of 490.9 square mm.
490.9 square inches for a 25-inch diameter circle.
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
Area = 1/4*Pi*d2 = 0.25*3.14*52(25) = about 19.63ft2
