radius
pi r2 = 3 x 2 pi r Divide each side by pi r, giving r = 3 x 2 so radius is 6 inches and diameter 12 in.
The minute hand will usually be about 1/8 inch from the edge of the clock face. The hand plus 1/8 inch is the radius, so the diameter of the clock face would be 12-1/4 inches (diameter is radius x 2). The formula for finding circumference is Pi x D, where Pi = 3.1416 and the D is the diameter. Using the formula C = Pi x D: C = 3.1416 x 12.25 = 38.4846 inches would be a good estimate of the circumference of the clock face.

9 Pi is the circumference.
you need to know the radius or the diameter of the clock remember the circle must be within reach of the hour hand next you workout the formula pie*d or 2pie*r * 24
