Answer:
B. 5
D. 9
F. 7
Step-by-step explanation:
A triangle has sides a,b and c:
And a < b+c , b < a+c and c < b+a
Here, a = 4 and b = 7
Find c?
So, 4 < 7+c , 7 < 4+c and c < 4+7=11
A. 11 False, it doesn't satisfies inequality third
B. 5 True
C. 17 False, it doesn't satisfies inequality third
D. 9 True
E. 3 Not true it doesn't satisfies second inequality
F. 7 True
Answer:
12.55
Step-by-step explanation:
To solve for area using circumference, use the formula:

where a=area and c=circumference
We know the circumference is 12.56, so

Once you plug this in and solve, you get 12.55 for the area.
Hope this helps! :]

Answer:
It is not arithmetic, so therefore there is no common difference
Step-by-step explanation:
An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. There is no constant term in the above pattern.
