Step-by-step explanation:
3/8 written as an decimal is <span>0.375</span>
-------------------------------------------------
Volume of cone:
-------------------------------------------------
Volume = 1/3 πr²h
-------------------------------------------------
Find Height:
-------------------------------------------------
Given that the radius = 5 and the volume = 100, we will substitute these values into their respective variable and solve for height.
Volume = 1/3 πr²h
100 = 1/3 π (5)²h
h = 100 ÷ 1/3π(25)
h= 4 units (Nearest whole number)
-------------------------------------------------
Answer: The height is 4 units.

Answer:
Option D. 
Step-by-step explanation:
we know that
The area of a trapezoid is equal to
![A=\frac{1}{2}[b1+b2]h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5Bb1%2Bb2%5Dh)
we have
substitute the values
=44\ cm^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B8%2B14%5D%284%29%3D44%5C%20cm%5E%7B2%7D)
