A barrel in the shape of a cylinder has a height of 4.5 feet and a diameter of 6 feet. The barrel is filled with oil to 6 inches from the top of the barrel.
So what is the volume of the oil in the barrel?

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

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.

Which is the focus of a parabola with equation y2=4x
