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.
the answer is 6mm by jay jay
6mm would be 0.6 cm because 10mm is 1cm and 1 cm -4 would be 0.6
dear me,,, 6mm, sigh!

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
Area = 113.1mm2

six tenths 1cm = 10mm 0.6cm = 6mm 0.6 = 6/10
the answer is 6mm by jay jay
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.
6mm would be 0.6 cm because 10mm is 1cm and 1 cm -4 would be 0.6
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.
