Answer:
V ≈ 527.79
Step-by-step explanation:
Formula is V= πr2h
therefore
V = π * 4 * 2 * 10.5
V = π * 8 * 10.5
V ≈ 527.79
coordinate of B= (2+3,0) = (5,0)
by pythagoras' theorem,
height of triangle^2 + half length of AB^2 = AC^2
height of triangle^2 = 3^2-1.5^2
height of triangle ^2= 6.75
height of triangle= √6.75
coordinates of C= (1.5,√6.75)
Allen's claim that we do not have enough information to solve for angle 1 is incorrect
<h3>How to calculate the measure of angle 1</h3>
Given that:
Angle 2 = 110 degrees
Angle 1 and angle 2, are the only angles on the straight line.
So, we have:

Substitute 110 for angle 2

Subtract 110 from both sides

The measure of angle 1 is 70 degrees.
So, we can conclude that Allen's claim is incorrect
