Parameterize the curve of intersection of the surfaces so that the direction is clockwise when viewed from above. Include a sket

Olegator [25]

Answer:

Answer is attached in images

Step-by-step explanation:

Given:

x+z=1 and

$z=4-x^{2} -y^{2}$

Now,

$1-x=4-x^{2} 2-y^{2} 2\\x^{2} -x+y^{2} \\x^{2} -x+1/4+y^{2} =3\\(x-1/2)^{2} +y^{2} =3+1/4\\(x-1/2)^{2} +y^{2} =(\sqrt(13)/2)^{2}$

Which is circle with center (1/2,0) radius

$\sqrt{13/2}$ take, $x=1/2+\sqrt{3} /2 cos\alpha \\y=\sqrt{13}/2 sin\alpha 0\leq \alpha \leq 2\pi$

Now,

Find the area of the shaded portion intersecting between the two circles.

stich3 [128]

Answer:

Area shaded portion = 16/3 π - 8√3

Step-by-step explanation:

The shaded portion consists of 2 equal segment

∵ Two circles have the same radii = 4

∵ The the length of the common chord of the two circles = 4

∴ The central angle of each segment = π/3 (60° equilateral Δ)

∵ Area segment = area sector - area Δ

∵ Area sector = 1/2 r²Ф = 1/2 × (4)² × π/3 = 8/3 π

∵ Area Δ = 1/4 s² √3 = 1/4 × (4)² × √3 = 4√3

∴ Area segment = 8/3 π - 4√3

∴ Area shaded portion = 2(8/3 π - 4√3) = 16/3 π - 8√3
