I got 314 too, you have to use your formula a=pi(r2)
Answer:
Using the slope-intercept form, the slope is 0 .
Step-by-step explanation:
The given point is (0,-12).
It is required to tell whether the point is an x-intercept or a y-intercept.
Recall that the first coordinate of a coordinate point represents the x-coordinate, while the second coordinate represents the y-coordinate.
The x-intercept is the point where the y-coordinate is zero.
The y-intercept is the point where the x-coordinate is zero.
Notice that the given point has an x-coordinate of zero; this means that the given point is a y-intercept.
The point is a y-intercept.
I believe the answer is cos^2 theta. Sec^2 theta on the right side of the equation is the inverse of Cos^2 theta, so multiplying the two together will get you 1. Cos^2 theta * Tan^2 theta = Sin^2 theta, and Cos^2 theta * 1 = Cos^2 theta. This all leads to the third and last step in the picture above.
