Answer:
the area of the circle is 25π or about 78.54 yards
Step-by-step explanation:
Area of circle=πr^2, r being radius
r=5
5^2=25
25π≈78.54 yards
Correct me if im wrong but the answer is (B) hope this helps!
Point D is the midpoint of the outer circle that we aim to find the area of
The circle has a diameter of WZ and radii of WC and CZ
We know that YZ=YD=10 cm
Let DC be

and CY be

The radius of the outer circle can be written as

or

which we can equate to find the value of





Therefore, the radius of the circle is

And hence the area of the circle is

=324
Answer:
Area of bigger rectangle = length x breadth = 12 x 9 = 108 square cm
Area of small rectangle = length x breadth = 8 x 5 = 40 square cm
Area of the shaded region = Area of big rectangle - Area of small rectangle
= 108 - 40 = 68 square cm
That is a fraction
or it could be another one
