Answer:
! means factorial . For example 3! (factorial 3) = 3*2*1 = 6
Answer to 14C3 is 364
Step-by-step explanation:
14! = 14*13*12*11*10*9*8*7*6*5*4*3*2*1
14C3 = 14*13*12*11*10*9*8*7*6*5*4*3*2*1 / 3*2*1 * 11*10*9*8*7*6*5*4*3*2*1
= (14*13*12) / 3*2*1
= 14*13*2
= 364
Third is y=-2x-2, second is y+4=-1(x-3), first is y+5=-1(x+4)

Answer:
Diameter: 12
Circumference: 37.68
Area: 113.04
Step-by-step explanation:
The radius of the circle is 6 cm.
To find the diameter of a circle, multiply the radius by 2.
6 × 2 = 12.
12 is the diameter.
----------------------------------------------------------------------------------------------------------------
Formula for the circumference of a circle: πd (diameter).
In other words, to find the circumference of a circle, multiply the diameter by pi.
**3.14 IS A SUBSTITUTE FOR PI**
12 × 3.14 = 37.68
Therefore, 37.68 cm is the area of the circle.
----------------------------------------------------------------------------------------------------------------
Formula for area of a circle: πr² (r = radius).
3.14 × 6 × 6 = 113.04
Therefore, 113.04 cm² is the area of the circle.
