find the area of the shaded region (circle inside a square) [Solved]

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
