Question

3. Luis wants to calculate the volume of his globe. The globe is in the shape of a sphere, as represented in

Answer 1

The measure which is closest to the volume of Luis's globe is; 6301.2in³

Volume of a sphere

If the circumference of the globe along the equator is 72inches along the equator;

• C = 72 = 2π× r

Hence, the radius of the globe can be evaluated as;

• r = 72/(2×3.14)

• r = 72/6.28

r = 11.46in.

On this note, the Volume, V of the globe is;

• V = (4/3) × π × r³

• V = (4/3) × 3.14 × 11.46³

V = 6301.2in³
