Here is a better picture. any help is appreciated. please

Diagram 1:

Small Circle Radius - 2in

Large Circle Radius - Not Given

Hence, It is not possible to find the area of the external portions [If you can give me the radius of larger circle, i can edit my answer.]

Diagram 2:

Side of Square = 10cm

Diameter Of Semi-Circle = 10cm [Diameter Of Semi-Circle =Side of Square]

2 Similiar Semi-Circles = 1 Full Circle

Hence,

Area Of Square - Area of 1 Full Circle = Area of Shaded Zone

10² - (π x r²) cm² = Area of Shaded Zone

10² - (π x 5²) cm² = Area of Shaded Zone [Radius = Diameter/2 = 10/2 = 5cm]

100 - 25π cm² = Area of Shaded Zone

25 (4-π) cm² = Area of Shaded Zone

Diagram 3:

Side Of Square = 10cm

Diameter Of Circle = 10cm

Radius Of Circle = 10/2 = 5cm

Area Of Square - Area Of Circle = Area of Shaded Zone

10² - (π x r²) cm² = Area of Shaded Zone

10² - (π x 5²) cm² = Area of Shaded Zone [Radius = Diameter/2 = 10/2 = 5cm]

100 - 25π cm² = Area of Shaded Zone

25 (4-π) cm² = Area of Shaded Zone [Same Answer as Diagram 2]

Diagram 4:

Radius Of Circle - 7cm

Diagonal Of Square - 7 + 7 = 14cm

Area Of Circle = π x r² = π x 7² = 49π cm²

Area Of Square When Diagonal Is Given = d²/2 = 7²/2 = 49/2 = 24.5cm²

Area Of Shaded Region = Area Of Circle - Area Of Square = 49π - 24.5 [Answer]

Hope I Helped,

This took me a while..

the answer is d. (1.2, -4.7) on edgn

hope this !
