|dw:1333646493820:dw|A town plans to build a skating rink.A diagram of the proposed rink is shown below.Find the rink area in square feet.
first find the area of the rectangle.Next find the area of the two half-circle ends.
(remember that two halves makes a whole!) add the results
listen here u had halves
i think the fig. is enough to tell u wat to do just apply the formula
as for finding area of rect. 2r x lenght
as u are gicen r=50 and lenght=200
similary u are having two halve make a circle
so area of circle= pie r^2
now wen u ll get the area of circle divide it by 2 as u need to find the area of halves ok
