c is the answer, no noah used the diameter instaed of the radius in the calculations
Noah used the diameter instead of the radius in the calculations and did not use the correct formula for the volume of a sphere option (C) and option (D) are correct.
What is a sphere?
It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.
We have the diameter of the sphere = 9 units
The radius of the sphere r = 4.5 units
We know the expression for the volume of a sphere is given by:
[tex]\rm V = \frac{4}{3} \pi r^3[/tex]
[tex]\rm V = \frac{4}{3} \pi (4.5)^3[/tex]
[tex]\rm V =27\pi[/tex] cubic units
Noah used the diameter instead of the radius in the calculations and Noah did not use the correct formula for the volume of a sphere.
Thus, Noah used the diameter instead of the radius in the calculations and did not use the correct formula for the volume of a sphere option (C) and option (D) are correct.
