Will mark 1. the surface area of a cube is decreased from 150 cm2 to 96 cm2 . by what factor has the volume changed? 2. a store owner wants to create giant ice cream cones that contain 3 times the volume of a traditional cone . how should he change the radius and height of the traditional cone?

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.
