  The circumference of a circular stage is 157 feet. Katie wants to paint the stage black. IF she paints the stage at a rate of 400 square feet per hour, how long would it take for her to paint the entire stage? Round to the nearest hour.

There is two questions...... the title does not match the post.?

 

4 wheeler   pi 2r = pi * 2 * 14 = ........inches in one rotation

 

Stage

  Circumference = 157 = 2 pi r       r = 24.987 ft      area = pi r^2 = 1961.5 ft^2

     1961.5 ft^2 / 400 ft^2/hr = 4.9 hrs to paint ~~5 hours to paint
