1. To solve this problem, you must aplpy the formula for calculate the volume of a sphere, which is:
V=4/3(πr)
V is the volume of the sphere.
r is the radius of the sphere.
2. You must calculate the radiius. You have that the beach <span>ball has a diameter of 18 inches, then:
r=diametert/2
r=18 inches/2
r=9 inches
3. When you substitute r= 9 inches into the formula, you obtain:
</span><span>
V=4/3(πr)
V=3053.62 inches</span>³

Answer: There are 18 students in a van and 24 students in a bus.
Step-by-step explanation:
Let the number of students in the van be 'x' and the number of students in bus be 'y'.
Then, According to the question, we have the following system
Multiply 2 to both the sides of equation (2), we get
Subtract equation (1) from equation (3), we get
Substitute value of x in (1), we get
Hence, there are 18 students in a van and 24 students in a bus.
