That would be (171 + x) / 2....what u do to find the average is add up all the numbers, then divide by how many numbers there are.
Its A. 10,000 divided by 250 is 40. Then multiply 40 by 2 and you get 80
10,000 / 250 = 40
40 * 2 = 80
80= A.
Answer: The coordinates would be (4,-5)
Answer:
V =113.04
Step-by-step explanation:
A sphere has a surface area of 113.04
SA = 4 pi r^2
113.04 = 4 pi r^2
Let pi 3.14
113.04 = 4 *(3.14) r^2
113.04 = 12.56 r^2
Divide each side by 12.56
113.04/12.56 = r^2
9 = r^2
Take the square root of each side
3 =r
We want to find the volume
V = 4/3 pi r^3
V = 4/3 (3.14) 3^3
V =113.04
The Method is that you add 1 block horizontally to the 2nd row of the figure every time you make a new one.
