Question 298847
The minute hand on a grandfather clock cuts and angle of 30 degrees as it moves
 from 12 to 1 on the clock face.
 If the minute hand is 16.7cm long, what is the area of the clock face over
 which the minute hand moves from 12 to 1?
:
Find the area of the clock dial
A = {{{pi*16.7^2}}}
A = 876.16 sq/cm
:
Find the area covered by the hand as it travels {{{1/12}}} of the dial
{{{876.16/12}}} = 73.0 sq/cm
