Joyce goes walking on a track shaped like the solid line in the diagram shown. Find the total area enclosed by the track. A. 2,956.5 square meters
B. 2,250 square meters
C. 3,309.75 square meters
D. 2,826 square meters

A

Step-by-step explanation:

πr^2

π * 15^2 = 706.858347

75 X 30 = 2250

706.858347 + 2250 = 2956.858347

b

step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
