The equation for the area of a circle is A = PI x r^2

R = radius, which is half the diameter = 23/2 = 11.5

Area = 3.14 x 11.5^2

Area = 3.14 x 132.25

Area = 415.265 square cm.

Answer:

y = -x +3

Step-by-step explanation:

The point-slope form can be a useful place to start.

y -k = m(x -h) . . . . . line with slope m through point (h, k)

You require the line ...

y -(-4) = -1(x -7)

y = -x +7 -4 . . . . . . . . eliminate parentheses, add -4

y = -x +3 . . . . . . . . . slope-intercept form
