Final answer:
To calculate the cost of steel to make one ball, we need to find the volume of the ball and then multiply it by the cost per unit volume of the steel.
Step-by-step explanation:
To calculate the cost of steel to make one ball, we need to find the volume of the ball and then multiply it by the cost per unit volume of the steel.
The formula for the volume of a sphere is V = (4/3)πr^3, where r is the radius of the sphere.
In this case, the radius is given as 0.056 m. So, V = (4/3) * 3.14 * (0.056)^3 = 0.000721 m^3.
Next, we multiply the volume by the cost per unit volume of the steel, which is $0.008 per m^3. So, the cost of the steel to make one ball is 0.000721 m^3 * $0.008/m^3 = $0.00000577.
Therefore, the steel will cost $0.00000577 to make one ball.
