A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh
NeTakaya

Answer:

15 cm.

Step-by-step explanation:

It is given that,

Central angle =\dfrac{7\pi}{10}

Arc length = 33 cm

Formula for arc length :

s=r\theta

where, s is arc length, r is radius and \theta is central angle in radian.

Substitute s=33 and \theta=\dfrac{7\pi}{10} in the above formula.

33=r\left(\dfrac{7\pi}{10}\right)

Multiply both sides by 10.

330=7\pi r

Divide both sides by 7\pi.

\dfrac{330}{7\pi}= r

Put \pi=3.14

\dfrac{330}{7(3.14)}= r

15.0136= r

r\approx 15

Therefore, the radius of the circle is 15 cm.

DeAngelo is training for a half marathon. Today he is running 13.25 miles. He jogs for the first half hour at a rate of 5.5 mile
klemol [59]
The first thing we must know is the following definition:
  d = v * t
  Where,
  d: distance
  v: speed
  t: time
  Therefore, the total distance traveled in this case is:
  (5.5) * (0.5) + (1.5) * p = 13.25
  Rewriting:
  2.75 + 1.5p = 13.25
   Clearing the value of p we have:
  p = (13.25-2.75) / (1.5)
  p = 7
   Answer:
  an equation representing this situation is: 
  2.75 + 1.5p = 13.25 
  DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour
