A pulley is 1.2 ft. in diameter. (show all work) a) Find the diameter the load will rise if the pulley is rotated 630 degrees. Find the exact distance in terms of π and then round to the nearest tenth of a foot. b) Through how many degrees should the pulley rotate to lift the load 24 ft. Round to the nearest degree.
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
