Answer: 267.947 (or 267.95) inches^3
Step-by-step explanation:
The formula for the volume of a sphere is 
.
To find your radius (r), divide the diameter of 8 inches by 2. <em>The radius is 4 inches.</em>
Plug in your numbers to the volume equation to get 
. The first step is to cube 4 (4*4*4) to get <em>64</em>. Now your equation is 
.
Multiply 3.14 and 64 to get <em>200.96</em>. The equation is now 
or 
.
Multiply the numerators (4 * 200.96) and denominators (1 * 3) to get a final equation of 
.
Finally, divide 803.84 by 3 to get the final answer of 267.947 in^3.
These two quantities obviously refer to a picture or drawing that shows how they're related to each other. Without the picture, they're not related, and there's no answer.

Answer:
y = 0, y = 
, y = 7
Step-by-step explanation:
Factor out 
from each term
( 3
- 22
+ 7) = 0 , that is
(3y² - 22y + 7) = 0 ← factor the quadratic
Consider the factors of the product of the coefficient of the y² term and the constant term which sum to give the coefficient of the y- term
product = 3 × 7 = 21 and sum = - 22
The factors are - 21 and - 1
Use these factors to split the y- term
3y² - 21y - y + 7 ( factor the first/second and third/fourth terms )
3y(y - 7) - 1 (y - 7) ← factor out (y - 7) from each term
(y - 7)(3y - 1)
Then
(y - 7)(3y - 1) = 0
Equate each factor to zero and solve for y
= 0 ⇒ y = 0
3y - 1 = 0 ⇒ 3y = 1 ⇒ y =
y - 7 = 0 ⇒ y = 7
