Answer:
<em>A= 1256</em>
Step-by-step explanation:
<u>The formula for area of a circle is </u>
1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. <em>40/2 = 20. </em>
<em>2. </em>Then, plug in the values into the area formula. <em>A= 3.14</em>
3. Solve.<em> A= 1256</em>. (Remember that 20 squared is <em>20x20</em>)
Distance =
so plug in the coordinates and you will get 14.14 units

Answer:
x-intercept: -14/9
y-intercept: 7
Step-by-step explanation:
This is one of the easiest forms for finding intercepts. To find the x-intercept, set y=0 and divide both sides by the coefficient of x.
-9x = 14 . . . . . set y=0
x = -14/9 . . . . divide by -9
__
To find the y-intercept, set x=0 and divide both sides by the coefficient of y.
2y = 14 . . . . set x=0
y = 7 . . . . . . divide by 2
The x-intercept is -14/9; the y-intercept is 7.
