Answer:
-1/3 sqrt(21)
Step-by-step explanation:
1/3 sqrt(21) - 2/3 sqrt(3) * sqrt(7)
We know sqrt(a) * sqrt(b) = sqrt(ab)
1/3 sqrt(21) - 2/3 sqrt(21)
Factor out sqrt(21)
sqrt(21) (1/3-2/3)
sqrt(21) (-1/3)
-1/3 sqrt(21)
Your best bet is A. 524
Use the formula V=4/3(pi)r^3 or

Not sure if that made sense but you need to multiply to radius(cubed) by pi and divide it by 4/3
Next time just google the volume formula of a sphere
Answer:
45 degrees
Step-by-step explanation:
Inscribed angles are always half of the value of the central angle, therefore half of 90 degrees would be 45 degrees.
