Answer:
- 1,563.5 in³
- 904.8 yd³
- 2,144.7 mm³
- 1,288.2 cm³
- 434.9 in³
Step-by-step explanation:
The formula for the volume of a sphere is ...
V = (4/3)πr³
When you have several of these calculations to do, it is convenient to let a graphing calculator or spreadsheet do them. A spreadsheet can do the rounding for you, too. The results are attached. The units are the cube of the units of the radius.
<u><em>Example calculation</em></u>:
(4) Radius = diameter/2 = 13.5 cm/2 = 6.75 cm
V = (4/3)π(6.75 cm)³ = 4.18879 × 307.547 cm³ = 1288.2 cm³
Note that the constant (4/3)π ≈ 4.18879 remains the same for each calculation. All you need to do is multiply that by the cube of the radius.
Answer:
jim is 24 years old, Mark is 20 years old
Step-by-step explanation:
This prompt can be set up using this equation:
Let's represent Mark's age by variable m and Jim's age by variable J.
j + m = 44
m + 4 = j
m = j - 4
j + (j - 4) = 44
2j - 4 = 44
2j = 48
j = 24
So, jim is 24 years old, meaning mark must be 20 years old. 20 + 24 results in 44 years old together.

Answer:
For the first one it has to be evaluated by the function.
So the answer for (A) is = 6x + 2 = 2 ( x +4 ) -2 =
= 2x + 6
1 = 2x + 6
x= -7/13 3) x=1 4) x= -1 =
x = - 7/13 = 3
