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

Pls make brainliest I need 1 more to reach expert

Graph 1 represents 2 inches represents 60 miles.

What is Graph?

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

The Latin term datum, which means "something provided," is where the word data originated.

Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorized, and visually portrayed.

We have

2 inches = 60 miles

The above statement shows that when there is 2 units on x axis then 60 units on y- axis.

From the given graph the graph 1 shows that 2 units on x axis and 60 units on y- axis.

Graph 2, 2 units on x axis then 125 units on y- axis.

Graph 3, 2 units on x axis then 115 units on y- axis.

Graph 4, 2 units on x axis then 175 units on y- axis.
