Answer:
Step-by-step explanation:
The curve x = f(y)
The area of the surface around the y-axis from y = a → y = b is:
From the given curve:
; assuming the region bounded by the curve is 0 ≤ y ≤ 1
So;
5x = y³
The differential of the above equation Is:
Now, we have the area of the surface produced around the curve through the y axis from the region y = 0 to y = 1
∴
Let make
It implies that:
when y = 0 ;
u = 5
when y = 1;
The equation can be written as:
26:100
