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: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
From the question, we are informed that Amy has 10 yd of fence to put around a tree and that she uses all the fence to make six sections that are the same length.
The expression that will be equal to the length of one of these sections in yards will be:
= 10 yards / 6
= 1.67 yards or 1 2/3 yards
This means that any option that you see that is different from the answer above will be the answer based on your question.
The answer can be one of 3:
in exact form: 351/16
in decimal form: 21.9375as a mixed number: 21 15/16
:)))
let's say
A(-3,1) B(-3,5) C(4,1)
we need to find the perimeter of ABC for that we find each of the sides
AB BC and AC
there is a formula to find the distance between 2 poins
let's say that a point has the structure A(x1,y1) where x=-3 and y=1 and B(x2,y2) where x2=-3 and y2=5
AB=
AB=
AB=
AB=4
we do the same thing for AC and BC
AC=
AC=
AC=7
BC=
BC=
BC=
BC=
The perimeter is equal to the sum of the sides
P=AB+AC+BC=4+7+
=11+
