Answer:
30
Step-by-step explanation:
third side is the hypotenuse since it is opposite to 90 degree.
using pythagoras theorem
a^2 + b^2 = c^2
24^2 + 18^2 = c^2
576 + 324 = c^2
900 = c^2
= c
30 = c
therefore third side is 30.
A rectangle has dimensions of 9 in. by 8 in. Find the exact volume (in cubic inches) of the solid of revolution formed when the
rectangle is rotated about its 8 in. side.Incorrect: Your answer is incorrect.in3
1 answer:
V = 162π in^3
Explanation:
Since rotation a rectangle on its side result to a cylinder.
We'll use the formula for the volume of a cylinder with 8in being the height (since the rectangle is rotated around that side) and 9 in as the diameter.
Data:
Radius : r = diameter / 2 = 9/2 = 4.5 in
Height : h = 8 in
Formula:
