The volume of a sphere is 4/3*pi*r^3, therefore:
V = 4/3*pi*(12/2)^3 ~= 904m^3 = B

V = 4/3 pi. r^3 where r is the radius of the sphere. Since diameter is given as 12m, radius will be half of it, viz. 6 m.
V = 4/3 . 3.14 6^3 = 904.32 m3 or 904 m3 approx. So B is the right choice for answer.

The volume of a sphere is defined as (4/3)* pi * r^3 or
r=d/2 or 12/2 = 6
6^3 * 3.14 * (4/3) = 904.32
B is your answer

D=12 so r=6 then
V = (4/3)*pi*r^3
= (4/3)*pi*6^3
=904 m^3

r = 6 m
V = (4/3) x Ï x 6³ m ³
V = 904 m ³
OPTION B

volume = 4/3 Ï r³
v = (4/3) * 3.14 * 216
v = 904.32 m³

B
Vol = 4/3 * pi * r^3
And I see we have an @sshole giving thumbs down to correct answers.

radius = 6 metres
volume =(4/3)*(pi)*[(r)^3]
therefore
volume = (4/3)*(3.14)*[(6)^3]
volume = (1.33)*(3.14)*(216)
volume = 902.059
units of volume is
(metre)*(metre)*(metre) = (metre)^3
near by ans approximately is
904 m3
the answer is second option
