Answer:
The volume of the solid is π/40 cubic units.
Step-by-step explanation:
Please refer to the graph below.
Recall that the area of a semi-circle is given by:
The volume of the solid will be the integral from <em>x</em> = 0 to <em>x</em> = 1 of area A. Since the diameter is given by <em>y</em>, then the radius is <em>y/2</em>. Hence, the volume of the solid is:
Substitute:
Simplify:
Integrate:
![\displaystyle V=\frac{1}{2}\pi \left[\frac{x^5}{20}\Big|_0^1\right]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cfrac%7B1%7D%7B2%7D%5Cpi%20%5Cleft%5B%5Cfrac%7Bx%5E5%7D%7B20%7D%5CBig%7C_0%5E1%5Cright%5D)
Evaluate:
The volume of the solid is π/40 cubic units.
Do you have a protractor? If so, use it and place the center whole, that is located at the bottom, and place it on the dot of the angle. where the arrow hits, is your angle degree. You should be able to identify the angle type.
Answer:32

Answer:
9/10
Step-by-step explanation:
Very simple, Keep It, Change It, Flip it
Do 3/4 X 6/5 and you should get your answer
STEP 1:
find the length of the sides of the square
AREA FORMULA (for a square)
x= side
A=x^2
225=x^2
take square root of both sides
15 feet= x
STEP 2:
find perimeter
PERIMETER FORMULA (for a square)
x= side of square
P= 4x
use x value from step 1
P= 4(15 ft)
P= 60 feet
ANSWER: The perimeter is 60 feet.
Hope this helps! :)
