Step-by-step explanation:
S = ∫ 2π y ds
ds = √(1 + (dx/dy)²) dy
ds = √(1 + (8y)²) dy
ds = √(1 + 64y²) dy
S = ∫₁² 2π y √(1 + 64y²) dy
S = π/64 ∫₁² 128y √(1 + 64y²) dy
S = π/64 [⅔ (1 + 64y²)^(³/₂)] |₁²
S = π/96 (1 + 64y²)^(³/₂) |₁²
S = π/96 (1 + 256)^(³/₂) − π/96 (1 + 64)^(³/₂)
S = π/96 (257√257) − π/96 (65√65)
S = π/96 (257√257 − 65√65)
Answer:
43.98
Step By Step Explanation:
Answer:
Answer is 25ft.
Step-by-step explanation:
l=20ft.
h=16ft.
let 'w' be x.
then
l=√w2+h2
or l=√x2+(16)2
squareing on both side.
or (20)2=√(x+16)2
or 400=x+16
or x=400/16
or x=25.
so that the value of W is 25ft.
