What is the circumference of the following circle The local public pool is a rectangle with two semicircles.

The area of the rectangle is...

Using 3.14 for π and rounding to the nearest meter, the area of each half circle is ... m2.

The area of the surface of the pool is...m2.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
