What is the length of the arc if: 11. r=10 n=20 A15(pi)/ 7 B13(pi)/ 5 C16(pi)/ 2 D11(pi)/ 4 E 10(pi)/ 9 F 9(pi)/ 4 12. r=3 n=6 A

Vilka [71]

Step-by-step explanation:

The formula for arc length [for the angle in degrees] is:

$L = 2\pi r \left(\dfrac{n}{360}\right)$

here,

$n$ = degrees

$r$ = radius

using this we'll solve all the parts:

r = 10, n = 20:

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (10) \left(\dfrac{20}{360}\right)$

from here, it is just simplification:

2 and 360 can be resolved: 360 divided by 2 = 180

$L = \pi (10) \left(\dfrac{20}{180}\right)$

10 and 180 can be resolved: 180 divided by 10 = 18

$L = \pi \left(\dfrac{20}{18}\right)$

finally, both 20 and 18 are multiples of 2 and can be resolved:

$L = \pi \left(\dfrac{10}{9}\right)$

$L = \dfrac{10\pi}{9}$ Option (E)

r=3, n=6:

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (3) \left(\dfrac{6}{360}\right)$

$L = \dfrac{\pi}{10}$ Option (D)

r=4 n=7

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (4) \left(\dfrac{7}{360}\right)$

$L = \dfrac{7\pi}{45}$ Option (C)

r=2 n=x

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (2) \left(\dfrac{x}{360}\right)$

$L = \dfrac{x\pi}{90}$ Option (D)

r=y n=x

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (y) \left(\dfrac{x}{360}\right)$

$L = \dfrac{xy\pi}{180}$ Option (E)

I need help please !

The last one is the answer.

If the number is no less than 6, that means that it is not any smaller than 6.

That narrows the answer down to x > 6 and x >= 6. The difference between these two choices is that x>6 means that x cannot equal 6, while the last choice is greater than OR equal to 6.

Since we are looking for when the minimum value for x is 6, x >= 6 is the answer.

Rewrite the following multiplication problem using the associative property and then show that both results will be the same.

densk [106]

<u>Answer:</u>

The answer is the same i. e., 4.375 in all the cases as shown below.

<u>Step-by-step explanation:</u>

$\frac {3}{7} \times \frac {5}{6} \times \frac {1}{4}$

= $\frac {35}{8}$

= $\frac {3}{7} \times \frac {1}{4} \times \frac {5}{6}$

= $\frac {5}{6} \times \frac {1}{4} \times \frac {3}{7}$

= $\frac {5}{6} \times \frac {3}{7} \times \frac {1}{4}$

= $\frac {1}{4} \times \frac {5}{6} \times \frac {3}{7}$

= $\frac {1}{4} \times \frac {3}{7} \times {5}{6}$

= 4.375 (answer)
