Do you mean to the nearest ten? If so, then it would be 60. Look to the right of the number you are to round, if it's 5 or more then round up. If it's 4 or less then round down. If it's a zero, then do nothing. The numbers following the one you are rounding get changed to zero's.

The first thing you need to do is find the radius of the semicircle. To do that you look to see that the width of the rectangle is the same as the radius. Once you have the Area of a Semicircle calculated multiply it by 3. then, we know that the other length of the rectangle is 3 diameters of a semicircle this means that you multiply the radius of 7 by 6 which gives you 42. You take the area of the rectangle (294) and subtract the area of the 3 semicircles(230.79) Which gives you the answer of 63.21cm^2
