Answer:

The answer is 16π ft²

Step-by-step explanation:

What he need to do is "act" like there is a triangle in the circle, so the radius is 4, 4*2=diameter, 8, thats the length of the triangle, the height of the triangle is 4, now we find the area of the triangle, 8*4=32, 32/2=16

This is for anyone who needs it in the future

Graph -3x + 9y = -27​
Svetllana [295]

Answer:

Step-by-step explanation:

The first step you want to do is get one variable by itself. We are going to start by isolating y by itself.

-3x + 9y = -27

9y = 3x - 27

y = 1/3x - 3

By isolating y by itself, you now have a function written in slope-intercept form. To graph this function, you can draw a point at (0,-3), then use rise/run to go up 1 unit and over 3 units to the next point (3,-2). You can then draw a line based on this information.
