Given:
Consider the expression is 
.
To find:
The value of given expression.
Solution:
We have,
It can be written as
![[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bab%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D%5D)
![[\because \sqrt{-1}=i]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B-1%7D%3Di%5D)
Therefore, the value of given expression is 
.

x = 180 - 51 = 129
The statement, "the lateral surface area of cone A is exactly half of that of cylinder B" is: A. True.
<h3>What is the Lateral Surface Area of a Cone and a Cylinder?</h3>
Lateral surface area of cone = πrl
Lateral surface area of cylinder = 2πrh
Lateral surface area of cone A = πrl = πrh
Lateral surface area of cylinder B = 2πrh
This means the lateral surface area of cylinder B is twice that of cone A. Thus, lateral surface area of cone A is exactly half of that of cylinder B.
The answer is: A. True.

Answer:
A (Elise needs 7 quarts of ice cream)
Step-by-step explanation:
Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.
Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.
So 42 people divided by 6 equals 7 quarts.
i hope this helps !!
