Use pi•r^2 for the formula of a circle. filling it in, you get 3.14•64 which is 200.96
Answer:
Step-by-step explanation:
You could multiply all of equation A by 1/6 and all of equation b by -1/4 to get
A. x-3/2y=-1/3 and B. x+1/4y=/5/4, then subtract the equations from each other to solve
First, you need to set the equation equal to zero:
n^2 + 7n + 10 = 0
Now we factor. We need to find two numbers that add up to 7 and multiply to 10.
2 + 5 = 7
2 * 5 = 10
Now, we just need to write this as a polynomial:
(n + 2) (n + 5)
is our answer.
Hope this helps!
The answer is B, 7.6-(-1.7)=9.3
The mass should be 75.71 grams
To find density is D = M / V
So you would have to multiply the volume by the density
