Afire has started in a dry, open field and is spreading in the form of a circle. if the radius of the circle is increasing at the rate of 6 feet/min, find the rate at which the fire area is increasing when the radius is 150 feet.

Acircle has a circumference of 28.36 units what is the diameter of the circle

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.
