Question

Wesley makes spherical fish tanks with a diameter of 30. A customer requests a smaller tank with half the volume of the tank that Wesley usually makes.

What is the approximate diameter of the smaller tank?
Round to the nearest tenth.

Answer 1

23.8 is the diameter.

Explanation:

Answer 2

23.8

Explanation:

V = 4/3 π r³

V = 4/3 π (15)³

V = 4500 π

V = 4/3 π r³

4500 π / 2 = 4/3 π r³

1687.5 = r³

r ≈ 11.9

d ≈ 23.8
