Aregulation basketball has a diameter of about 9 inches. what is the best approximation of the volume of the ball?

382 in³

The basketball is spherical in shape and it's approximate volume (V) can be calculated using the formula

V = πr³ ( where r is the radius )

here the diameter = 9 ⇒ r = = 4.5

V = π × 4.5³

  = π  × 91.125 = 381.7 ≈ 382 in³

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
