Circle F has a diameter of 36m and = 240o. Find the length of . Leave your answer in terms of pi.

andrezito [222]

Answer:

So, the arc length is $24\pi$

Step-by-step explanation:

We are given

diameter =36m

so, we can find radius

$r=\frac{36}{2}=18m$

and angle as

$\theta=240$

Since, it is in degree

so, we can change it in radian

$\theta=240\times \frac{\pi}{180}$

$\theta=\frac{4\pi}{3}$

now, we can find arc length

$L=r\times \theta$

now, we can plug values

$L=18\times \frac{4\pi}{3}$

$L=24\pi$

in the diagram, AE is tangent to the circle at point a and secant DE intersects the circle at point C and D. the iines intersect

AlexFokin [52]

Recall the secant-tangent theorem, and you have
EA^2 = EC*CD
12^2 = 8*(x+10)
and now ED = EC+CD = 8+x+10

I suspect a typo somewhere in the murk above

A carpenter uses 10 1/2 ft of cedar for every 12 1/3 ft of redwood for a construction project. If the carpenter uses 5 1/4 ft of

motikmotik

Answer: 6 1/6

Step-by-step explanation:

1) First divide 10 1/2 = 5 1/4.

2) Then, since we divide 10 1/2 then we need to divide 12 1/3.

3) 12 1/3 divided by 2 = 6 1/6.

And there is your answer; 6 1/6
