Answer:

12.5π or ≈39.27

Step-by-step explanation:

The formula for finding the volume is V=πr^2*d (where h is the height and r is the radius).

Plug in the values: V=π(2.5)^2*2 (Diameter=2*Radius)

Solve: V=6.25π*2

V=12.5π

V≈39.27

Find the missing side lengths. Leave your answers as radicals in simplest form.

This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio $1:1:\sqrt{2}$ so we get

$u = v = 8$

We could have also gotten this using Trig:

$u = (8 \sqrt{2}) \sin 45^\circ = 8 \sqrt{2}/\sqrt{2} = 8$

$v = (8\sqrt{2})\cos 45^\circ = 8$

Or by recognizing u=v because remaining angle is 45 so this must be isosceles so

$u^2 + u^2 = (8 \sqrt{2})^2$

$2u^2 = 2 (8^2)$

$u = 8$

The answer is 1954. Letter C is correct
Solution:
If P(x) = 165,000
Then
165,000 = 55,000(x - 1945)^(1/2)
x= 1954

to check it, substitute x
165,000 = 55,000(1954 - 1945)^(1/2)
165,000 =165,000
