What is the approximate length of arc s on the circle below? 330 degrees central angle radius 12 feet

Aneli [31]

Answer:

$69.08\ ft$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=12\ ft$

substitute

$C=2\pi (12)$

$C=24\pi\ ft$

step 2

Find the approximate length of arc s

we know that

The circumference of the circle subtends a central angle of 360 degrees

using proportion

Find out the length of arc for a central angle of 330 degrees

$\frac{24\pi}{360}=\frac{x}{330}\\\\x=24\pi(330)/360$

$x= 22\pi\ ft$ ----> exact value

assume

$\pi =3.14$

$22\pi\ ft=22(3.14)=69.08\ ft$ ----> approximate value

Alek and Ann start walking around a track at the same time and at the same place. It takes Ann 6 minutes to walk around the trac

Yuki888 [10]

Answer:

3 3/7 minutes

Step-by-step explanation:

This calculated using the formula:

1/x + 1/y = 1/n

Where

x = Number of minutes it took Ann to walk = 6 minutes

y = Number of minutes it took Alek to walk = 8 minutes

n = Number of minutes it would take An and Alek to reach the starting point at the same time

1/6 + 1/8 = 1/n

Lowest Common Denominator = 24

4 + 3/24 = 1/n

7/24 = 1/n

Cross Multiply

7n = 24

n = 24/7

n = 3 3/7 minutes

It would take them 3 3/7 minutes to reach the starting point at the same time.

Is (0,4) a solution of 3x-4y=-4?

Debora [2.8K]

No. Because you have to put the 0 in the place of the X and the 4 in the place of the Y. Then do 3(0) which equals 0 then 0 - 4(4) 0 -16 is -16 and isn’t -4
