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

1149.8 m³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = πr³ ( r is the radius )

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

V = × 3.14 × 6.5³

   = × 3.14 × 274.625

   = ≈ 1149.8 m³ ( to the nearest tenth )

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
