c)4x + 5+ 7x +10=180
solve it like usually
for d) 3x + 15+12x=90
Answer:
Volume, V = 3367.6 cm³
Step-by-step explanation:
Given the following data;
Diameter = 18.6 cm
Radius = diameter/2 = 18.6/2 = 9.3 cm
Pie, π = 3.14
To find the volume of the sphere;
Mathematically, the volume of a sphere is given by the formula;
![Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%20Volume%20%5C%3B%20of%20%5C%3B%20a%20%5C%3B%20sphere%20%3D%20%5Cfrac%20%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D%20)
Where;
r is the radius of the sphere.
Substituting into the formula, we have;
![V = \frac {4}{3} * 3.14 * 9.3^{3}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%20%7B4%7D%7B3%7D%20%2A%203.14%20%2A%209.3%5E%7B3%7D%20)
![V = 4.186666667 * 804.357](https://tex.z-dn.net/?f=%20V%20%3D%20%204.186666667%20%2A%20804.357%20)
Volume, V = 3367.6 cm³
The dilation scale factor is applied to all lengths.
