Need Help On Number 8 class=

Sagot :

Answer:

36π

Step-by-step explanation:

diameter = 6 so radius is 3
[tex]\frac{4}{3}\pi r^{3}[/tex]
r = 3
[tex]\frac{4}{3}\pi *27[/tex]
= 36π

v = 4/3 pi r ^2 (radius squared)

the radius is half of the line you were given so its 3 (6/2=3)

so the answer solved is- 37.68 (using 3.14 as pi)
