Answer:

50.24 ft^2

Step-by-step explanation:

The radius of the circle in which the lawn sprinkler sprays water is 4 feet.

The formula to find the area of a circle is \pi r^2, where r = radius and π, in this case, is 3.14.

  • 3.14 × 4^2
  • 3.14 × 16
  • 50.24 ft^2

Therefore, the answer is 50.24 ft².

What is the slope-intercept equation of this line?
Gekata [30.6K]

Answer:

y = -2x+8

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/x2-x1)

m = ( -4 -8)/(6 - 0)

    = -12/6

   = -2

The y intercept is 8 from the point (0,8)

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -2x+8
