The circumference of a circle is 34.5575 units. a smaller circle has a diameter that is 3 units smaller, and an even smaller circle has a diameter that is 5 units smaller than the largest circle. all three circles share point m. find the area of the shaded region.

Large circle circumference  =  34.5575 units =large circle  diameter = 11 unitsmiddle circle  diameter =  8 unitssmall circle  diameter = 5 unitsarea of shaded region = middle circle area -small circle areaarea of shaded region =  pi * 8 ^2 / 4   minus pi * 5^2 / 4area of shaded region =  50.27 -19.63area of shaded region = 30.64 square units 

If gravity is one third on mars then weight also one third on mars
