Step-by-step explanation:

$2\pi {r}^{2} + 2\pi rh$

$2(3.14) {(20)}^{2} + 2(3.14)(20)(11)$

$6.28(400) + 6.28(220) \\ 2512 + 1381.6 = 3893.6 {mi}^{2}$

Solve for x. PLEASE HELP ASAP

Paha777 [63]

Answer:

x = 6

Step-by-step explanation:

the tangent- tangent angle UVW is half the difference of the intercepted arcs, that is

∠ UVW = $\frac{1}{2}$ (UW - WU ) , then

5x + 17 = $\frac{1}{2}$ (37x + 5 - (23x - 5) ) ← multiply both sides by 2

10x + 34 = 37x + 5 - 23x + 5

10x + 34 = 14x + 10 ( subtract 14x from both sides )

- 4x + 34 = 10 ( subtract 34 from both sides )

- 4x = - 24 ( divide both sides by - 4 )

x = 6

Use this equation to find dy/dx. 3y cos x = x2 + y2

Art [367]

Given: 3y cos x = x² + y²

Define $y' = \frac{dy}{dx}$

Then by implicit differentiation, obtain
3y' cos(x) - 3y sin(x) = 2x + 2y y'
y' [3 cos(x) - 2y] = 2x + 3y sinx)

Answer:
$\frac{dy}{dx} = \frac{2x+3y \, sin(x)}{3cos(x)-2y}$
