Answer:

21.46

Step-by-step explanation:

we know that 10yd is the diameter of the unshaded circle. so we will use this to find out the area of the circle. if a diameter of a circle is 10yd, the area is about 78.54 (considering that pi=3.14) to find the area of the shaded region, we can pretend that the entire square is shaded, and then take the unshaded away. if the square was completley shaded, the answer would be 100. but there is a circle inside of the square unshaded, with a area of 78.54, so we need to solve for 100-78.54. this results in our final answer, 21.46

Put it into a different form to make it easier.

[tex]3\frac{1}{9}p-\frac{1}{3}p+5[/tex]

Add the fractions. We need to figure out the LCM to figure out the common denominator. The LCM is 9 in this case.

[tex]3\frac{1}{9}-\frac{3}{9} +5[/tex]

I like to convert into imroper fractions. This is optional though.

[tex]\frac{28}{9} -\frac{3}{9} +5[/tex]

Get a common denominator. The LCM is 3.
