12.96 .12 times 8= .96 then add it to 12
Answer:
Area of the shaded region = 23.33 in²
Step-by-step explanation:
Area of a sector = 
Where θ = Central angle subtended by an arc
r = radius of the circle
Area of the sector BCD = 
= 52.36 in²
Area of equilateral triangle BCD = 
= 
=
in²
= 43.30 in²
Area of the shaded portion in ΔBCD = 52.36 - 43.3
= 9.06 in²
Area of sector CAD = 
= 39.27 in²
Area of right triangle CAD = 
= 
=
= 25 in²
Area of the shaded part in the ΔACD = 39.27 - 25
= 14.27 in²
Area of the shaded part of the figure = 9.06 + 14.27
= 23.33 in²
Circumference = 2×3.14×r
3.14 is pie and r is the radius.
To find the radius you divide the diameter by 2.
19 ÷ 2 = 9.5
2×3.14×9.5 = 59.66
Multiply 59.66 by 6 because ther are 6 pennies.
59.66 × 6 = 357.96 mm.
Answer: the exponent would be the 2

Answer:
the listed sequences have no common difference(s)
Step-by-step explanation:
The differences in the first sequence are ...
8, 10, -1, 19
These values are not equal, so there is no common difference.
__
The differences in the second sequence are ...
-3, 3, -3, 3
These values are not equal, so there is no common difference.
_____
The difference is the difference between a term value and the one before.
1 -(-7) = 8
3 -6 = -3
