Answer:
V ≈ 4577.204 cm^3
Step-by-step explanation:
Use the volume formula V=4/3πr^3 to find the volume. Since you need the radius but are given the diameter, divide it by 2 to get half.
21.4/2 = 10.7
Now plug that into the formula and solve:
V=4/3πr^3
V=4/3π(10.7)^3
V= 4/3π(1,092.7272)
V= 4/3 * 3432.903
V= 4 * 3432.903/3
V = 13731.614/ 3
V ≈ 4577.204 cm^3 or whatever unit is stated.
