Answer:

The error of this problem is that 6^3 is supposed to be 216 not 18. The volume is not about 75.4 cubic inches, but it is actually about 904.3

Step-by-step explanation:

When you evalulate 6^3 it is supposed to look like 6 x 6 x 6, which equals 216. However in this problem, the student does it as 6 x 3 = 18, which makes the whole answer wrong.

So the actual volume of the soccer ball is 904.3 cubic inches. A strategy to prevent from getting the problem wrong is to write 6^3 out as 6 x 6 x 6.

Answer: n=4

Step-by-step explanation:

Given

3n-(2+n)=6

Expand Parenthesis (REMEMBER TO CHANGE SIGNS)

3n-2-n=6

Combine like terms

2n-2=6

Add 2 on both sides

2n-2+2=6+2

2n=8

Divide both sides by 2

2n/2=8/2

n=4

Hope this helps!! :)

Answer:

y = 2x +13

Step-by-step explanation:

1. find the slope by using the formula y2-y1

--------

x2-x1

which is

23 - 19 4

------------ = --- = 2

5-3 2

2. finding the y intercept

so to find the y intercept you plug in the numbers to this formula

y-y1 = m (x-x1)

y - 19 = 2 (x -3)

y - 19 = 2x -6

+19 +19

y = 2x +13

Calculate the volume of each geometric shape:

pav-90 [236]

Answer:

a) 235.62in³

b) 904.78in³

Step-by-step explanation:

a) The formula to find the volume of a cylinder is:

$V = \pi r^2h$

We are given that r = 5 and h = 3, so we can just plug in and solve:

$V = \pi(5)^2(3) = 235.62in^3$

b) The formula to find the volume of a sphere is:

$V = \frac{4}{3}\pi r^3$

We are given that the diameter is 12in, which means that the radius (r) must be 6in (half the diameter). Now, we can plug in and solve:

$V = \frac{4}{3}\pi (6)^3 = 904.78in^3$
