Simplify.
Answer: 20.52
Step-by-step explanation:
Answer:
B C F
Step-by-step explanation:
If you reduce those answer and try to find the square roots, the decimals are terminating and never ending, while the others are perfect squares.
Volume of sphere = 4/3 x pi x r^3
904.32 = 4/3 x pi x r^3
Divide both sides by 4/3
678.4 = pi x r^3
Divide both sides by pi:
216 = r^3
Take the cubic root of both sides
R = 6
For this case what you should do is use the equation shown.
We have then:
n * A = 360
Where:
A=Angle
n: number of divisions.
We observe that there are eight divisions. Thus:
n = 8
We then clear the angle between each division
8 * A = 360
A = 360/8
A = 45 degrees
Answer:
The measure of the angle between the mirrors is:
A = 45 degrees
