Question

a 12cm * 2cm rectangle sits inside a circle with a radius of 8 cm what is the area of the shaded region?

Answer 1

Answer:

Is the shaded area what is left outside the rectangle and bounded by the circle? If so,

find the area of the rectangle = 12*12 = 144 unit^2

the area of the circle = pi*r^2 = 3.14*8^2 = 201.06 unit^2 (rounded to the nearest hundredth)

then the "shaded area" is the difference

201.06 - 144 = 57.06 unit^2

Answer 2

Answer:

first find radius of circle 2pi*r^2

2*22/7*8

=50.28cm

now find area of rectangle l*b

=12*2

=24cm

50.28-24

=26.28=ar of shaded region

Hope it helped
