Answer:

  3π/2

Step-by-step explanation:

It may help you to realize that the (x, y) coordinates of the point on the unit circle are ...

  (x, y) = (cos(θ), sin(θ))

Since you want sin(θ) = -1, look for the point on the unit circle that has a y-value of -1.  It is the point (0, -1) at the bottom of the circle, where the angle is shown as ...

  θ = 3π/2

A rectangular plot measures 20 ft. By 30ft. A 3ft wide side walk surrounds it. Find the area of the side walk
r-ruslan [8.4K]

Answer:

336 feet²

Step-by-step explanation:

If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².

If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².

To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².

Hope this helped!
