Answer:

Step-by-step explanation:

the answer should be 49mm
28*7 / 4 = 49
I think the answer is D but i could be wrong
Answer:
You aren't asked which variable to solve for.
If we're solving for x then
4x = 12y -8
x = 3y - (8/4)
If we're solving for y
-12y = -4x -6
12y = 4x +6
y = (x/3) + (1/2)
Step-by-step explanation:
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.
