Unformatted text preview: Final Exam for MAT 296 Spring 2005 READ THIS BEFORE YOU BEGIN! This examination contains 12 problems on 11 pages for a total value of 200 points. Point
values for each problem are indicated. It is your responsibility to make sure that all problems and pages are present! To receive full or partial credit, you MUST show correct work leading to the correct
answer. Unsupported answers will receive little or no credit. Nonsymbolic graphics calculators may be used in this examination. Calculators capable
of symbolic computations, such as the TI89 or TI92 may NOT be used. Print Your Name Instructor's Name Your Signature: — DO NOT WRITE IN THE TABLE BELOW (1) [15 pts] As shown below, a hemispherical tank of radius 10 feet is ﬁlled with water
to a depth of 5 feet. Set up an integral that can be used to ﬁnd the volume of water in the
tank. Do NOT evaluate the integral. (2) [15 pts] Consider the region in the ﬁrst quadrant bounded by y = x3, x=l, and the x—axis. Set up an integral that can be used to ﬁnd the volume of the solid obtained by
rotating the region about the line x=2. Include a carefully labeled sketch. Do NOT evaluate the integral. (3) [8 pts] Set up an integral that can be used to find the length of the curve given by
y = x% from the point (1,1) to the point (4, 8). Do NOT evaluate the integral. (4) [15 pts] A tank whose vertical cross section is a triangle is shown below. Assume
that the tank is 10 feet long and is full of water and that the water is to be pumped to a height 10 feet above the top of the tank. Set up an integral that can be used to find the work done in emptying the tank. The weight of water is 62 pounds per cubic foot. Do
NOT evaluate the integral. 6 feet 10 feet 5 feet (5) [16 pts] Determine each of the following limits. . (I l )
