Question 18

Multiple Choice

Set up and evaluate integrals for finding the moment about the y-axis for the region bounded by the graphs of the equations. (Assume ρ=1.\rho = 1 . )
y=64x2,y=0y = 64 - x ^ { 2 } , y = 0


A) My=0 M _ { y } = 0 by symmetry
B) My=88(64x2) 2dx=262,14415M _ { y } = \int _ { - 8 } ^ { 8 } \left( 64 - x ^ { 2 } \right) ^ { 2 } d x = - \frac { 262,144 } { 15 }
C) My=88(64x2) 2dx=524,28815M _ { y } = \int _ { - 8 } ^ { 8 } \left( 64 - x ^ { 2 } \right) ^ { 2 } d x = \frac { 524,288 } { 15 }
D) My=88(64x2) 2x2dx=65,53615M _ { y } = \int _ { - 8 } ^ { 8 } \left( 64 - x ^ { 2 } \right) ^ { 2 } x ^ { 2 } d x = \frac { 65,536 } { 15 }
E) My=88(64x2) dx=10243M _ { y } = \int _ { - 8 } ^ { 8 } \left( 64 - x ^ { 2 } \right) d x = \frac { 1024 } { 3 }
