Answer:
$64
Step-by-step explanation:
Since there were 4 of them and the coupons were $10 off, they saved a total of $40
To find how much they would have spent without the coupons, add 40 to 216:
216 + 40
= 256
To find the normal cost of one ticket, divide this by 4:
256/4
= 64
So, the price of one concert ticket without the coupon is $64

Answer:
 .
.
Step-by-step explanation:
Given information:
Radius of circle = 8 cm
Area of sector =  
Formula for area of sector is
 
where, r is radius and  is central angle in radian.
 is central angle in radian.
Substitute  and r=8 in the above formula.
 and r=8 in the above formula.
 
 
 
 
 
Therefore, the measure of the sector in radians is  .
