Hal says the volume of the sphere shown below is 36 cm3. Find the correct volume, using 3.14 for π. Round to the nearest hundredth. What was Hal’s likely error?

This question is incomplete because the diagram of the sphere was not shown. Find attached to this answer the diagram for the sphere.

a) The correct volume of the sphere = 113cm³

b) b) Hal's likely error was that

i) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)

ii) In addition to using the wrong formula, Hal did not use π in his calculation.

Step-by-step explanation:

a) The Volume of a Sphere = 4/3πr³

From the attached diagram, the radius of the sphere was given as = 3cm

π = 3.14

The volume of the sphere = 4/3 × 3.14 × 3³

= 113.04 cm³

We were told to round up to the nearest hundredth. Therefore, correct the volume of the sphere = 113cm³.

b) Hal's likely error was that

i) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)

ii) In addition to using the wrong formula, Hal did not use π in his calculation.

This means:

Surface Area of a Sphere = 4πr²

But Hal's used = 4r²

Where r = 3cm = 4 × (3cm)² = 36
