Is Noah's work correct? Explain. Yes, Noah's calculations are correct. No, Noah did not simplify correctly. No, Noah used the diameter instead of the radius in the calculations. No, Noah did not use the correct formula for volume of a sphere.

Answer :

Answer:

No, Noah used the diameter instead of the radius in the calculations.

V = 91.13Ï€

Step-by-step explanation:

Noah is working on a geometry problem that involves finding the volume of a sphere with a diameter of 9 units. His work is shown below.

V = πr3

V = π(9)3

V = π(729)

V = 972Ï€ cubic units

Is Noah’s work correct

Volume of a sphere, V = πr³

radius, r = diameter / 2

Diameter = 9 units

r = 9 / 2

= 4.5 units

Volume of a sphere, V = πr³

= π × 4.5³

= π × 91.125

= 91.125Ï€

Approximately 91.13Ï€

V = 91.13Ï€

No, Noah used the diameter instead of the radius in the calculations.

Answer:

no, he used radius instead of diameter
