Find the value of x. Then find the measure of Arc AN. Show work on a piece of paper.

Arada [10]

Answer:

a. x = 36

b. ∠(AN) = 144°

Step-by-step explanation:

All the angle in the circle should add up to 360°.

x + x + 4x + 4x = 360

2x + 8x = 360

10x = 360

x = 36

∠(AN) = 4x

∠(AN) = 4(36)

∠(AN) = 144°

mart [117]

Answer:

Step-by-step explanation:

P= 2(L) + 2(w)

1504= 2(525) + 2(w)

1540= 1050 + 2(w)

1540 - 1050= 2(w)

490 = 2(w)

490/2 = w

245 = w

w is y

L is 525

the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the <u>radius will be 3</u>

slant height is

$\sqrt{r^2+h^2}$

h is 4.7 and r is 3

$\sqrt{3^2+4.71^2} \\5.58427$

<u>slant height is 5.58427</u>

lateral surface area

$\pi r\sqrt{h^2+r^2}$

$\pi (3)\sqrt{4.71^2+3^2} \\52.63053$

<u>lateral surface area is 52.63053</u>

total surface area

$\pi r(r+\sqrt{h^2+r^2})$

$\pi 3(3+\sqrt{4.71^2+3^2})$

$80.90486$

<u>total surface area is 80.90486</u>
