<span>-3(2n+1)+7=-5
Multiply the number outside of the parenthesis with the numbers inside the parenthesis
-6n-3+7= -5
Subtract 7 from both sides
-6n-3=-12
Add 3 to both sides
-6n=-9
Divide -6 on both sides

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 $cm^{3}$
