Find the measure of the central angle of a sector if its area is 5 pi and the radius is 6
lesantik [10]
For this case we use the following formula
 Area of Sector = Area * radians of sector / 2 * pi radians
 Where,
 Area: it is the area of the complete circle.
 We have then:
 Area = pi * r ^ 2
 Area = pi * (6) ^ 2
 Area = 36pi
 Substituting values:
 5pi = 36pi * radians of sector / 2 * pi
 Clearing:
 radians of sector = ((5pi) * (2pi)) / (36pi)
 radians of sector = (10pi ^ 2) / (36pi)
 radians of sector = (10pi) / (36)
 radians of sector = (10/36) pi
 radians of sector = (5/18) pi
 in degrees:
 (5/18) pi * (180 / pi) = 50 degrees
 Answer:
 The measure of the central angle is:
 50 degrees

Can some help plzz I am stuck on this math problem!!
slega [8]

Answer:

60 points in 5 games

Step-by-step explanation:

plug the numbers of points scored into the top boxes,  so the boxes should look like  ( [8]+[11]+[12]+[16]+[n] ) then plug in the number of games he played in the bottom box     [5]                   so 8+11+12+16+n all divided by 5 has to = 12

5x12 = 60  

n= 60-8-11-12-16     n= 13
