Find the volume of a sphere with a radius of 1.8 yards. Leave your answer in terms of pi.
A. 23.34
B. 7.78
c. 7.2
D. 24.43
The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius.
Plugging in the given radius of 1.8 yards, we have:
V = (4/3)π(1.8)^3
= (4/3)π(5.832)
≈ 7.76
Therefore, the volume of the sphere is approximately 7.76 cubic yards.
The closest answer choice is B. 7.78.
