Answer:

3375 $\pi \\$ cubic centimeters

Step-by-step explanation:

Trick question: The largest piece is the entire cone.

First lets identify the equation for volume.

V= 1/3 h pi r^2

h=45

r=15

V= 1/3 45 * pi 15^2

v= 15* pi 225

3375 pi

You keep pi because the answer has pi.

Instructions: Find the measure of the indicated angle to the<br> nearest degree

Andru [333]

Answer:

See below.

Step-by-step explanation:

We want to find the unknown angle and we know the sides opposite to it and the hypotenuse. Therefore, we can use sine.

Recall that sine is the ratio of the opposite to the hypotenuse:

$\sin(\theta)=opp/hyp$

Plug in the numbers. The opposite is 20 and the hypotenuse is 55.

$\sin(\theta)=20/55$

Solve for theta (use a calculator):

$\sin(\theta)=20/55\\\theta=\arcsin(4/11)\\\theta\approx21.23\approx21\textdegree$
