Dunno the question... But I sure hope if you jump out of a plane the parachute is ALREADY inspected :d
Answer:
Volume of solid is
Step-by-step explanation:
We need to find the volume of solid formed by rotating the region bounded by the graph of , y-axis and the line y=3 about the line y=5.
Please see the attachment for figure.
Using Shell method,
where,
a=0 (Lower limit of solid)
b=4 (Upper limit of solid)
(Outer Radius of Shell)
r=2 (Inner radius of shell)
dx is thickness of shell
Volume of shell, dV=Area of shell x Thickness
Volume of solid
Thus, Volume of solid is
47 because a triangle needs to add up to 180° land you add the 43 plus the 90° and give you 133 and than you subtract the 180 by the 133 and it’s 47
