calculate the area of the shaded of region diagram.
thank you​

Answer 1

Answer:

Step-by-step explanation:

Given:

Side of square=8cm

Are of square=(side)^2=(8x8)cm^2=64cm^2

Radius of 1st quadrant=8cm

Area of quadrant=90/360x22/7x8x8

                            =1/4x22/7x64 = 22x16/7

Similarly,

Area of 2nd quadrant=22x16/7

Sum of quadrants=2(22x16/7)=704/7

Area of design=Sum of two quadrants-Area of square

(704/7-64)cm^2

(704-448/7)

256/7cm^2

36.57cm^2

Therefore, the area of design=36.57cm^2
