Answer:
2094.4 cm³
Step-by-step explanation:
The volume of a cone =πr²h/3
Where
r = radius = Diameter/2
Diameter = 20cm, radius = 20cm/2 = 10cm
Height = 20cm
Volume of a cone = π × 10² × 20/3
Volume of a cone = 2094.3951 cm³
Approximately to the nearest tenth = 2094.4 cm³
Therefore , the volume of a cone = 2094.4 cm³
Answer:
2
Step-by-step explanation:
Answer:
Step-by-step explanation:
All you need to do is isolate the x.
First, add 64 to both sides:
Then, take the square root of both sides:
Actually, that is:
Here's the reason for that. An example would be:
Here, you'd take the square root of both sides to solve for x.
Right? But X could also be a -2, because a negative times a negative is a positive.
Therefore, or
Answer:
781/1680
Step-by-step explanation:
Don't you have a calculator?
I assume that by (1 2/3 1/9), you mean (1+2/3)*(1/9)
Assuming that you put all necessary parentheses:
781/1680, approx. 0.4648809523809524
