Its a. becuase there are an equal
1) A 540 in^3
2) H 420in^3
3) 0.336 ft^3
for these first three the work you can show is just the three numbers multiplied together
4) T 240 in^3
5) U 126 ft^3
6) I 176 cm^3
for these just write 1/2a * c * h
a is the first number, c is the second number, and h is the third number
These are all I can help you with because I have homework to do
Hope this helps :)
Answer:
Diameter of a hemisphere: d = 2 * r ,
Volume of a hemisphere: V = 2/3 * π * r³ ,
Base surface area of a hemisphere: Ab = π * r² ,
Cap surface area of a hemisphere: Ac = 2 * π * r² ,
Total surface area of a hemisphere: A = 3 * π * r² ,
We know that for a hemisphere whose radius is 9 units, The volume is: Volume of hemisphere=2πr33 Volume of hemisphere = 2 π r 3 3
Step-by-step explanation:
First find the area of the parallelogram
Area of parallelogram = b x h
= 12 x 7
= 84
Then find area of kite
Area of kite = (xy)/2
= (7 x 12)/2
= 84/2
= 42
Now we are gonna subtract the area of the kite from the area of the parallelogram.
84 - 42 = 42
Therefore the area of the shaded region is 42.
The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.
