SerPSE10 1 A OP031 MI My A high fountain of water is located at the center of a circular pool as shown in the figure stands at the edge of the pool and uses a protractor to gauge the angle of elevation of the top of the fountain to be below. A student walks around the pool and measures its circumference to be 25.2 m. Next, the student 50.0° How high is the fountain? 10 1 A OP035 My Water is tant rate or cm③/s. The bow has a circular cross section, but does not have a uniform diameter. (That is, different horizontal cross sections taken at what is the rate (in cm/s) at which the water level nses at this diameter? (a) As the water fils the bowl, the water level reaches a point where the diameter of the bowl is di . 1.20 cm. cm/s (b) As the water continues to fil the bowl, the water level reaches a point where the diameter of the bowl is d, -7.00 cm. What is the rate (in cm/s) at which the water level rises at th cm/s 432 PM /28/2019 Tyne here to search

Answer 1

Given,

Circumference, C = 2 pi r = 25.2

Radius, r = 4.01 m

Tan(50) = height /radius = h/4.01

Height, h = 4.78 m
