Question

need help on number 8

Answer 1

Answer:

36π

Step-by-step explanation:

diameter = 6 so radius is 3
$\frac{4}{3}\pi r^{3}$
r = 3
$\frac{4}{3}\pi *27$
= 36π

Answer 2

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)
