Step-by-step explanation:
<u>Step 1: Define</u>
-19.2 = -3.6x + 2.4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2.4 on both sides: -21.6 = -3.6x
- Divide -3.6 on both sides: 6 = x
- Rewrite: x = 6
The correct answers are:
Exact volume =
in^3
Approximate volume = V = 33.51 in^3
Explanation:The volume of the sphere is:
Since r = 2 in
Hence
in^3
(exact)
V = 33.51 in^3 (approximate)
