A basketball has a diameter of 9.5 inches what is the volume of the basketball using 3.14 for pi.

Step2247 [10]

Answer:

448.69 in^3

Step-by-step explanation:

The volume of a sphere is given by the formula ...

V = (4/3)πr^3

We want to use diameter, so we can substitute r = d/2 into the formula:

V = (4/3)π(d/2)^3 = (4/(3·8))πd^3

V = (π/6)d^3

For the given numbers, ...

V = (3.14/6)(9.5^3) ≈ 448.69 in^3 . . . . volume of a basketball

Answer:

The ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.

Step-by-step explanation:

The quadratic function $h(t) = -4.9t^2 + 22t + 5.5$ represents the height of the ball above the ground, h(t), in meters, with respect to time, t, in seconds.

To find h(3), substitute t = 3 into the function expression:

$h(3)=-4.9\cdot 3^2+22\cdot 3+5.5\\ \\=-4.9\cdot 9+66+5.5\\ \\=-44.1+71.5\\ \\=27.4$

Meaning: the ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.
