A cylindrical vase has height 17 in. and radius 3 in. Find the exact surface area of the vase in terms of pi . Suppose a second vase has double the radius, but the same surface area. What is the height of this vase?

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
