Question

the diameter D of a sphere is 13m calculate the sphere volume V use the value 3.14 round your answer to the nearest tenth

Answer 1

Answer:

1149.8 m³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = $\frac{4}{3}$πr³ ( r is the radius )

Here diameter = 13, thus radius = 13 ÷ 2 = 6.5

V = $\frac{4}{3}$ × 3.14 × 6.5³

   = $\frac{4}{3}$ × 3.14 × 274.625

   = $\frac{4(3.14)(274.625)}{3}$ ≈ 1149.8 m³ ( to the nearest tenth )
