Question

5. Oscar needs to fill a sphere-shaped balloon with
helium. If the balloon has a diameter of 8 inches, what is
the total amount of helium that the balloon will hold to
the nearest tenth?
A. 2,143.6 in.3
B. 714.5 in.
C. 268.1 in.3
D. 150.7 in.

Answer 1

Answer:C=268.1

Step-by-step explanation:

The formula of volume for a sphere is V=4/3πr^3.

Make the diameter into radius.

8/2=4 in

Plug in 4 inches for the radius.

V=4/3π(4)(3)

Solve.

268. 08

Round to the nearest tenth.

268.1 inches=C
