Represent the volume of the cylinder with V1 and the volume of the sphere with V2
So, from the first statement: we have:

and

To solve for
, we simply substitute
for
in 




Hence, the volume of the sphere is

to find perimeter add the four sides
Answer: Number of 2 points question = 4, Number of 3 points question= 6.
Step-by-step explanation:
Let x = Number of 2 points question, y= Number of 3 points question.
As per given,
x+y = 10 ...(i)
2x+3y = 26 ...(ii)
Multiply 2 on both sides of (i), we get
2x+2y=20 ....(iii)
Eliminate (iii) from (ii), we get
y=6
Put value of y in (i), x+6=10
⇒ x=4
Hence, Number of 2 points question = 4, Number of 3 points question= 6.
REALLY????....It's 180..........wow
