Unformatted text preview: y = cos x and the xaxis, between x =π/ 2 and x = π/ 2. Make a sketch and use symmetry where possible. Math 166 Midterm Part II Page 3 3. (10 points) The corn in a grain silo, which has the shape of a right circular cylinder, is to be lifted out over the top edge of the silo. The silo is 20 feet in diameter and is 30 feet high. If the corn in the silo has a uniform depth of 25 feet, how much work is done in lifting all of the corn out of the silo? [Use δ lb / ft 3 for the (weight) density of the corn.] Math 166 Midterm Part II Page 4 4. (10 points) Find the length of the parametric curve x = 3 t 2 , y = 2 t 3 , 0 ≤ t ≤ 2....
