It is 9 inches because the formula for the area of a circle is πr2 where the r represents the radius of the circle
The pi can be canceled out =
πr2 and 81 π leaving with
R2 and 81
The r2 represents a square number. So square root 81 and you would result in 9 as your answer

Answer:
D. y = 2x + 1
Step-by-step explanation:
To find the slope, you first have to find the change of y over x, and in this case, you can plainly see that each one is equal to 2. So, that means that the slope is 2. You then can use the slope to find y when x is equal to 0. In this case, y = 1 when x = 0, so that means that the y-intercept is 1. Hence, the final answer is D.
