the square is the shaded part and theres a circle inside. and the sides of the square are 10 cm. i dont know how to find the area.

Ashaded = Asquare Acircle

= 10^2 (pi*10^2)/4

= 21.46 cm2

ANSWER = 21 sq.cm

the length o fa side of the square is the same as the diameter

solution = area of square area of circle

area of square =1010=100sq.cm

diameter of circle =10cm (circle fits perfectly inside square right)

radius=5cm

area of circle=22/7 x 5^2=79sq.cm ( rounded off)

area of shaded region= 100-79=21sq.cm

so (10)(10)-pi(5)^2

100-25pi

100-78.5

21.5 sq. cm

A = s

A = 10

A = 100

ANSWER = 21 sq.cm

This is pretty easy.

A = r

A = 5

A = 25

ANSWER = 21 sq.cm

Assuming your circle has its edges touching the square.

7.85 m**2

ANSWER = 21 sq.cm

area of square-area of circle. since the side of the square is 10 the radius of the circle is 5

Find the area of the circle:

Diameter of the circle = 10 cm

(Diameter drawn = to equal equal sides of square)

Radius = 5cm (Diameter = 1/2 radius)

Area of a circle = pi *r*r

Area = 3.14 * 5 * 5

Area=3.14*25

Area of circle=78.5 cm^2

Area of square =side * side

Side = 10 cm

Area = 10*10

Area =100cm^2

Area of shaded portion = Area of square Area of Circle

=100 78.5

=21.5cm^2

Assuming your circle has its edges touching the square.

so (10)(10)-pi(5)^2

100-25pi

100-78.5

21.5 sq. cm

You get this by doing Area square Area Circle

side^2-.5side^2*pi=

10^2-5^2*pi=

100-25pi=21.5 cm^2

so (10)(10)-pi(5)^2

100-25pi

100-78.5

21.5 sq. cm

solution = area of square area of circle

area of square =1010=100sq.cm

diameter of circle =10cm (circle fits perfectly inside square right)

radius=5cm

area of circle=22/7 x 5^2=79sq.cm ( rounded off)

area of shaded region= 100-79=21sq.cm

7.85 m**2

the length o fa side of the square is the same as the diameter

solution = area of square area of circle

area of square =1010=100sq.cm

diameter of circle =10cm (circle fits perfectly inside square right)

radius=5cm

area of circle=22/7 x 5^2=79sq.cm ( rounded off)

area of shaded region= 100-79=21sq.cm

so (10)(10)-pi(5)^2

100-25pi

100-78.5

21.5 sq. cm

Now, for the circle, the diameter of that circle is the same length as a side of the square. So the radius is than 5cm.

You get this by doing Area square Area Circle

side^2-.5side^2*pi=

10^2-5^2*pi=

100-25pi=21.5 cm^2
