Question 875098: Two circles have the same center. The radius x of the smaller circle is 5 units less than the radius of the larger circle. How many more square units does the larger circle cover? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Area of bigger circle - area of smaller circle= extra area covered
pi*(x+5)^2-pi*x^2
pi(x^2+10x+25)-pi*x^2
10pi*x+25pi sq. units
