Step-by-step explanation:
Write the equation 11x-24+3x-20=180. The answer is 16.
Examine the given terms of the sequence. Is every term the same multiple of the previous term? If so, that multiplier is called the "common ratio," r
If "a" is the first term of the sequence, then a_n = (a)(r)^(n-1).
They are 7 points away from each other.
The calculation for circumference is 2πr or 2 × π (pi=3.14) × radius of a circle
Since the diameter of this circle is 7cm, and the radius is half of the diameter, 7 ÷ 2 = 3.5
So, 2×3.14(π)×3.5=21.98
