70685.8mm2 (rounded to the nearest tenth)

The area of a circle can be found by the formula: A = pi * radius2, or A = pi * (diameter/2)2

Thus, A = pi * (300mm/2)2 = (22500*pi) mm2, or approximately 70685.8mm2

Area of a 600mm dia circle?

Area of a circle = pi x radius squared. The radius of a circle is equal to half the diameter, in this case 600/2 = 300mm. So area = pi x 3002 = 282743 mm2 (nearest mm2)

What is area of a circle that measures 3.50 from side to side?

The measurement of a circle from "side to side" is the diameter. The area of a circle is 2*Pi*r where r is the radius. Since diameter = 2*r, A=Pi*d where d is the diameter. A=3.14159265*3.5 ~= 10.996 square units.
