The answer is -3
The correct answer is the option D, which is: <span>D. 78 cm; 39 cm; 30.3π cm
The explanation is shown above:
1-The formula for calculate the circumference of a circle is:
C=2</span>πr
78π=2πr
2- The radius is:
r=78π/2π
r=39 cm
3- The diameter is:
D=39 cm x 2
D=78 cm
4- The arc length is:
arc length=(140°π/180°)(39 cm)
arc length=30.3π cm

Step-by-step explanation:
Answer:
An ice cream cone with 5 scoops cost is, $4.5
Step-by-step explanation:
As per the statement:
An ice cream stand uses the expression
to determine the cost of an ice cream cone that has x scoops of ice cream.
⇒ Cost of an ice cream cone C(x) =
.....[1]
Given: x = 5 scoops
We have to find the cost of an ice cream cone with 5 scoops cost.
Substitute the given value of x =5 in [1] we have;
C(5) = 
C(5) =
= 2 + 2.5 = $4.5
Therefore, an ice cream cone with 5 scoops cost is, $4.5
313,626 = 2 * 152,346 + 8934
152,346 = 17 * 8,934 + 468
8,934 = 19 * 468 + 42
468 = 11 * 42 + 6
6 divides 42, so the GCD of 313,626 and 152,346 is 6.
