Answer: The area of the circle is 452.16 square units.

Step-by-step explanation:

To find the area of a circle you need to use the area of a circle formula. The formula is A= π x r^2.

π= 3.14

r= 12

The r is radius which is half of the diameter. When you apply the formula you get :

A = 3.14 x 12^2

A= 3.14 x 144

A= 452.16

Graph the line with slope -3 passing through the point (3,-4)
Vinvika [58]

Given: \textsf{Slope = -3, Passes through (3, -4)}

Find:  \textsf{Equation in slope-intercept form}

Solution: The first step that we need to take is to plug the given values into the point-slope formula which would help us out since we have both the slope and a point.  Using that we would then distribute on the right side of the expression and then subtract 4 from both sides which would isolate y.

<u>Plug in the values</u>

  • y - y_1 = m(x - x_1)
  • y - (-4) = -3(x - 3)

<u>Distribute</u>

  • y + 4 = (-3 * x) + (-3 * - 3)
  • y + 4 = -3x + 9

<u>Subtract 4 from both sides</u>

  • y + 4 - 4 = -3x + 9 - 4
  • y = -3x + 9 - 4
  • y = -3x + 5

Therefore, after plugging in the values and completing the rest of the steps we were able to determine that equation of the data provided would be y = -3x + 5.
