Answer:
y=-4+8
Step-by-step explanation:
The question "how much space is inside a solid?" is actually asking about the volume of that solid.
The volume of a cone is given by

where h is the height of the cone, and r is its radius.
So, you only need to plug in the values:

Answer:
x²+(1/x²) = 47
Step-by-step explanation:
by identity : (a+b)² = a²+b²+2ab
(x+1/x)²= x²+(1/x)²+2(x)(1/x)
(x+1/x)²= x²+(1/x²)+2....(1)
since : (x²+1)/x = 7
(x²/x) +(1/x) = 7
x + (1/x )= 7
put the value for : x +(1/x) in (1) :
49 = x²+(1/x²)+2
x²+(1/x²) = 47
