<span>Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).</span>

1. A professional basketball used for league play has a diameter of 25 cm. Which of the following is closest to the volume of th
yKpoI14uk [10]

Answer:

V = 8,181.23 cm^{3}

Step-by-step explanation:

Unfortunately, we are not given any answer choices to choose from but using the information provided we can find the actual volume of the basketball. A basketball is made in the shape of a sphere and the formula for the volume of a sphere is the following...

V = \frac{4}{3} * \pi  * r^{3}

radius of a circle/sphere is half of it's diameter. Since we are provided the diameter size we simply divide it by 2 which would give us 12.5cm. Now we simply plug this value into the formula and solve for V.

V = \frac{4}{3} * \pi  * 12.5^{3}

V = \frac{4}{3}  * \pi  * 1953.125

V = 8,181.23 cm^{3}
