Hello there!
We are going to follow the volume of a sphere since a volleyball is a sphere. V=4/3πr^3 is the formula for finding the volume of a sphere. The only unknown value is r, or the radius. We find the radius by halving the diameter.
8/2 = 4, so we have a radius of 4 inches.
Place the value of 4 in for r - V = 4/3 x π x (4)^3
Now solve.
V = 4/3 x π x (4)^3
Start by squaring 4.
V = 4/3 x π x 64
Next, multiply 4/3 by 64. (<em>you can do it in any order since there are no parenthesis</em>)
V = π x 85.33
Lastly, multiply 85.33 by pi.
V = 268.08
So, your answer is approximately 268.08, since we used rounding it is not exact. I hope this was helpful and have a great rest of your day! :)
Answer:
10.
Step-by-step explanation:
If you mean the number of combinations of 2 from 5 it is
5*4 / 2*1
= 10.
Answer: c) 2x-5
We can represent two times micheal’s age as 2x, and 5 years younger would be you subtract 5
So the answer is 2x-5
Answer:
Option A
Step-by-step explanation:
A does not have an x that has 2 or more outputs
Answer:
Step-by-step explanation:
We can use the equation y=mx+b to solve this problem.
First, we know the 'm' or slope of the line, so we'll substitute that into the equation.
Now, let's solve for b. We already have x and y values - x= -3 and y=4. Let's substitute that into y=x+b and solve.
Finally, let's plug the slope and y intercept ('b') back into y=mx+b.
That's the answer to this problem.
I hope this helps.
