Answer:
V = π /2 volume units
Step-by-step explanation:
Volume of y = √x bounded by y = x and y = 1
y = √x
limits of integration ( see Annex )
By simple inspection limits of integration are x = 0 to x = 1
or y = √x and y = x
solving these two equations
x = 0 y = 0 x = 1 y = ± 1
V = ∫ π*f(x)²*dx
V = π * ∫₀¹ x*dx = π * x²/2 |₀¹
V = π * (1/2) - 0
V = π /2 volume units

The gardens perimeter is 12 meters.
Explanation:
- The garden has a 4m length and a 2m width. The perimeter of any given rectangle is two times the sum of the length and the width of the same rectangle.
- Perimeter = 2 × (length of the rectange + width of the rectangle)
Perimeter = 2 × (4m + 2m) = 2 × (6m) = 12 meters.
- So the gardens perimeter is equal to 12 meters.
- Ramond needs to buy a fence for a garden whose parameter is 12 meters.
