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:
Last one

Answer:
$4.78
Step-by-step explanation:
subtract 6.10 from 30 = 24.90
then divide it by 5
ans : $4.78
The given line is in point-slope form.
All options are also in point-slope form.
We can read the slope off the point-slope form easily.
The slope is 2.
A perpendicular to that line must have slope -1/2.
Only one line in the options has slope -1/2 and it's option B.
