Inside a square plot, a circular garden is developed which exactly fits in the square plot and the diameter of the garden is equal to the side of the square plot which is 28 metres. What is the area of the space left out in the square plot after developing the garden?

Options

A. `698m^2`
B. `646 m^2`
C. `840 m^2`
D. None of these

Answer

D

Explanation

Area of the space left out = Area of square - Area of circle

`=(56)^2-22/7xx28xx28`
`=56(56-(11xx28)/7)`
`=56(56-44)`
`=56xx12`
`=672 m^2`
