Find the volume of a sphere with a radius of 1.8 yards. Leave your answer in terms of pi. round your answer to the nearest hundredth, if necessary.
a 23.34π yds^3
b 7.78π yds^3
c 24.43π yds^3
d 7.2π yds^3
The formula for the volume of a sphere is V = (4/3)πr^3, where r is the radius.
Plugging in the given radius of 1.8 yards, we have:
V = (4/3)π(1.8^3)
V = (4/3)π(5.832)
Now, we can simplify and calculate the volume:
V ≈ 7.78π yds^3
Therefore, the correct answer is b) 7.78π yds^3.
