The volume of the spherical ball will be 4 · π · 3² · 10⁶ cubic cm. Then the correct option is A.
The complete question is attached below.
<h3>What is the volume of the sphere?</h3>Let r be the radius of the sphere.
Then the volume of the sphere will be
V = 4/3 πr³ cubic units
The radius of the sphere is 3·10² cm.
Then the volume of the spherical ball will be
V = 4/3 πr³
V = 4/3 π(3 x 10²)³
V = 4/3 · π · 3³ · 10⁶
V = 4 · π · 3² · 10⁶ cubic cm
Then the correct option is A.

Answer:
The correct answer is A.
Step-by-step explanation:
The area of a rectangle can be calculated using the following formula:
If we know that the area measures and one side of the figure measures 4.2 m, we can say that:
We isolate the side we don't know:
So I = 9 m
To know the perimter of a rectangle, we use the following formula:
Answer:
The answer is below
Step-by-step explanation:
A) i)
For Anna initially, she has $0 from making 0 envelopes. After making 400 envelopes she has $20. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (400, 20). Using the equation of a line:
The table is:
x: 200 400 600 800 1000
y: 10 20 30 40 50
ii)
For Jason initially, he has $0 from making 0 envelopes. For every 250 envelopes he has $10. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (250, 10). Using the equation of a line:
The table is:
x: 200 400 600 800 1000
y: 8 16 24 32 40
The graph is plotted using geogebra online graphing
b) From the table above we can see that Anna makes more stuffing than Jason.
c) Anna has a savings of $100. Hence this can be represented by the points (0, 100) and (250, 10). Using the equation of a line:
We can see from the graph that there is a y intercept at 100. That is the earnings starts from 100.
The equation of a line is given as y = mx + b, where m is the slope and b is the y intercept (initial value)
For the first graph, the slope is 1/20 and the initial value is 0 while for the second graph the slope is 1/15 and the initial value is 100
D) The line pass through (10, 10) and (100, 40), hence:
