Answer:

"If the shape is not a rectangle, then the shape doesn't has four sides."

Step-by-step explanation:

Given conditional statement is,

" Is a shape has four sides, then the shape is a rectangle."

Here we have two statements:

Statement p → A shape has four sides

Statement q → The shape is a rectangle.

Contrapositive of the statement will be:

If \sim q then \sim p.

Therefore, contrapositive will be,

"If the shape is not a rectangle, then the shape doesn't has four sides."

A regulation basketball has a diameter of about 9 in. What is the best approximation for the volume of this ball? 3050 in³ 382 i
Mandarinka [93]

The best apporximation for the volume of this ball is 382 cubic inches.

<h3>What is the volume of the ball?</h3>

The volume of the ball is calculated by the formula V = 4 / 3πr³. This formula is the same in the whole world.

Given

A regulation basketball has a diameter of about 9 in.

The radius of the ball is;

\rm Radius = \dfrac{Diameter}{2}\\\\Radius=\dfrac{9}{2}\\\\Radius=4.5\ inches

The volume of the ball is;

\rm Volume =\dfrac{4}{3}\pi r^3\\\\Volume=\dfrac{4}{3} \times 3.14 \times 4.5^3\\\\Volume =\dfrac{144.53}{3}\\\\Volume = 381.51\\\\Volume = 382 \ In^3 \ apporx

Hence, the best apporximation for the volume of this ball is 382 cubic inches.
