Volumes of Spheres

Question

r= 4.5
Which choice could you use to find the volume of the given sphere? (π = 3.14)
A. V= 4(3.14) (4.5)^3
B. V= 4/3 (3.14) (4.5)^2
C. V= 4/3(3.14) (4.5)^3
D.V=(3.14) (4.5)^3

Answer 1

C. V= 4/3(3.14) (4.5)^3

B 286.1 cubic units286.1 cubic units
C 381.5 cubic units381.5 cubic units
D 401.6 cubic units

Answer 3

To determine the volume of the sphere:

V = (4/3)πr^3
V = (4/3)(3.14)(4.5)^3
V = (4/3)(3.14)(91.125)
V ≈ 381.5 cubic units

Therefore, the answer is C. 381.5 cubic units.
