Find the length of the diameter of circle C. 1" 2" 4"
2 answers:
The diameter of a circle can be found with the formula:
So diameter is two times or twice the radius.
In the given figure, in circle C , the measure of radius KC is 2 inches.
As we know diameter is two multiplied by radius, so we can multiply our radius KC with 2 to get the diameter of circle C.
Plugging the value of radius in the given formula we have,
So the diameter of circle C is 4 inches.
Answer: Diameter is 4 inches for the circle C. Last option 4" is the right choice.

Answer:
29
Step-by-step explanation:
The n th term of an arithmetic sequence is
• = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
d = 1 - 7 = - 5 - 1 = - 6 and a₁ = 7, = - 161, hence
7 - 6(n - 1) = - 161 ← solve for n
7 - 6n + 6 = - 161
13 - 6n = - 161 ( subtract 13 from both sides )
- 6n = - 174 ( divide both sides by - 6 )
n = 29
There are 29 terms in the sequence
