Answer:
C. 7790.83 cm^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
We know the radius is 12.3
Using 3.14 for pi (This will give us an approximation, not an exact value)
V = 4/3(3.14) (12.3)^3
=7790.82984 cm^3
In 5 years the demand will be about $19.33 million.
<u>Given:</u>
The formula for compound growth is
, where <em>E</em> is ending value, <em>B</em> is beginning value, <em>R</em> is rate of growth, and <em>T</em> is the amount of time.
Demand for electrical services (<em>B</em>) = $12 million per year
Growth rate <em>(R) </em>= 10%
<em>T</em>= 5 years
<u>Computation</u>:
Substitute all values in the formula , we get
![E = 12 \times (1 + 0.1)^5\\\\=12(1.1)^5\\\\=12\times1.61051=19.32612\approx19.33](https://tex.z-dn.net/?f=E%20%3D%2012%20%5Ctimes%20%281%20%2B%200.1%29%5E5%5C%5C%5C%5C%3D12%281.1%29%5E5%5C%5C%5C%5C%3D12%5Ctimes1.61051%3D19.32612%5Capprox19.33)
In 5 years the demand will be about $19.33 million.
