Step-by-step explanation:
<span>In a Metro there are:
20 rows of seats
18 seats in a row
and $5 per ticket
Using commutative property of Multiplication:
Therefore.
=> (20 x 18) x 5 = 5 x (18 x 20)
=> 360 x 5 = 5 x 360
=> 1800 = 1800
Therefore, they have $1800 income.</span>

<u>Given</u>:
Given that the radius of the sphere is 9 cm
We need to determine the volume of the sphere.
<u>Volume of the sphere:</u>
Let us determine the volume of the sphere.
The volume of the sphere can be determined using the formula,

where r is the radius of the sphere.
Substituting r = 9 in the above formula, we get;




Thus, the volume of the sphere is 972π cm³
Hence, Option B is the correct answer.
