Circumference of circle = π x d
diameter = 3x2= 6m
3.14 x 6 = 18.84m (circumference)
Area of a circle = π x r x r
=3.14 x 3 x 3
=28.26m2 (area)
We have been given that a sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed. We are asked to find the volume of the sphere.
We know that height of sphere is equal to its radius. This means that
.

Using
, we will get:


Upon comparing volume of sphere and volume of cylinder, we can see that volume of sphere is
times volume of cylinder.




Therefore, the volume of the sphere would be 28 cubic meters.

Answer: 7/10</h3>
==========================================================
Explanation:
There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.
If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.
The empirical probability of it not raining on the first of May is therefore...
1 - (probability it rains)
1 - (3/10)
(10/10) - (3/10)
(10-3)/10
7/10
We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.
I believe the correct answer from the choices listed above is option D. The graph <span>G(x) as compared to the graph of F(x) would be that the </span><span>graph of G(x) is the graph of F(x) stretched vertically and shifted 5 units down. 2 is a stretch factor and -5 is the shift downwards of the graph. Hope this answers the question.</span>
100 divided by 50 is 2.
So multiply the change by 2, so 2 times 3.
Answer is 6 percent.
