Answer:
75 in³
x: 30
y: 20 35
Step-by-step explanation:
v = πr²h / 3
v = 3.14 * 3² * 8 / 3
v = 3.14 * 9 * 8 / 3
v = 75.36 in³
Rounded
v = 75 in³
---------------------
x increase by 10 for each step
y increases by 7.5 for each step
x: 0 10 20 30 40
y: 5 12.5 20 27.5 35
(7 - b) + (3b + 2)
Open the parentheses (this is a simple addition question so there's no need to do anything)
7 - b + 3b + 2
Rearrange (not necessary but makes it easier)
3b - b + 7 + 2
2b + 9
-T.B.
Answer: The value of the sine of ∠C is 0.28.
Step-by-step explanation:
Let's draw a triangle again (see the picture below).
Remember SOHCAHTOA? It's:
-sin = opposite/hypotenuse
-cos = adjacent/hypotenuse
-tan = opposite/adjacent.
We need to use sin in here.
The sin of C is
