The width of the square is 7 cm. This is also the diameter of the circle.
To find the area of the square, you do 7², which is 49 cm².
To find the area of a circle, you do πr².
The radius is half the diameter, so it's 7 ÷ 2, which is 3.5 cm.
π3.5² ≈ 38.4845100065 cm².
The shaded region is the area of the square minus the area of the circle.
49 - 38.4845100065 = <span>10.5154899935, but because you're using 3.14 to approximate pi, the closest answer is 10.54 cm</span>².
The answer is 10.54 cm².
Remember that an exponent means repeated multiplication.
The exponent of 4 means you have four 
's mutiplied together:
And then each exponent of 2 inside means you have two 
's multiplied inside each set of parentheses.:
There are 8 b's there when you expand this out.
Answer:
Step-by-step explanation:
F(0) = -1/5
f(4) = 7/17
f(4) - f(0)
average rate of change = --------------
4 - 0
(7/17) - (-1/5)
average rate of change = ---------------------
4
52/85
average rate of change = ---------
4
average rate of change = 52/85 *4
average rate of change = 208/85
