Three sisters run a lawn mowing service. Their biggest customer is an award-winning gardener. The focal point of her lawn is a semicircular plot 400 meters in diameter. She insists that it be mowed in strips parallel to the diameter. Therefore, to optimize their time, the sisters divide the plot into three regions of equal area using two cuts parallel to the diameter. Determine the equations (of the form y=k) for the two parallel cuts.   Which pair of cuts divide the space into three equal areas? y=40 & y=100 y=53 & y=111 y=65 & y=118.

Question

Three sisters run a lawn mowing service. Their biggest customer is an award-winning gardener. The focal point of her lawn is a semicircular plot 400 meters in diameter. She insists that it be mowed in strips parallel to the diameter. Therefore, to optimize their time, the sisters divide the plot into three regions of equal area using two cuts parallel to the diameter. Determine the equations (of the form y=k) for the two parallel cuts.

 

Which pair of cuts divide the space into three equal areas?

  1. y=40 & y=100
  2. y=53 & y=111
  3. y=65 & y=118.
