Three circles are placed in a rectangle with width 14cm. Find the area of the shaded region. Use the value 3.14 for pi, and do not round your answer. Be sure to include the correct unit in your answer.

Question

I'll assume that the circles are congruent. 

|dw:1348346022932:dw|

if the width is 14 cm then the diameter of each circle is 14cm and the radius is 7cm

the length of the rectangle will be 3 diameters of 3 x 14 cm

so the Area of the rectangle = 7 x 14

Area of the circles = 3 x (3.14 x 7^2)

the difference would be the shaded area. As I don't have a diagram to work off.

ok i did it and i got 363.58

campbell_st · Answer

um I got 126.42

anonymous · Answer

first you multiply the are of the rectangle which is 98 then the area of the circle which is 3(3.14x 49) and i got 461.58 then do you subtract them from each other ?? I'm confused
