d = 2r = 12 mm
Area of a circle = pi*r2 , where pi = 3.14 and r is the radius of the circle. We have diameter(d) = 12mm so, radius(r) = d/2 = 6mm On putting the values we get Area = 3.14*62 = 3.14*36 = 113mm2
A 6mm circle has a diameter of 6 millimeters, which is about 0.24 inches. To visualize it, it's slightly smaller than a dime, which has a diameter of approximately 18mm. The radius of the circle would be 3mm, or 0.12 inches. Overall, it's a small circle, typically used in applications like jewelry making or precision engineering.
Area = 113.1mm2
An ordinary pencil is one example.
A cent (penny) is circular so the "greatest distance" is simply its diameter. Since 1858, all US cents have had a diameter of 19.05 mm.

Area of a circle = pi*r2 , where pi = 3.14 and r is the radius of the circle. We have diameter(d) = 12mm so, radius(r) = d/2 = 6mm On putting the values we get Area = 3.14*62 = 3.14*36 = 113mm2
A 6mm circle has a diameter of 6 millimeters, which is about 0.24 inches. To visualize it, it's slightly smaller than a dime, which has a diameter of approximately 18mm. The radius of the circle would be 3mm, or 0.12 inches. Overall, it's a small circle, typically used in applications like jewelry making or precision engineering.
Area = 113.1mm2
If the diameter is 12mm then the radius is 6mm. The area of a circle is pi X r2. Therefore pi X 36 mm2 = about 113.0973 mm2 = area of the circle. Don't forget units!! pi is about 3.1416.
Area = pi*32 = 28.274 square mm to 3 d.p.
Area of a circle with radius r is pi*r2 where pi is the irrational number approximately equal to 3.14159. You now have all the information required to answer this and other similar questions.
