Answer:
A = 11²/{4π}
Step-by-step explanation:
The circumference equation is C = 2πr. Thus, r = C / (2π), and:
C² (22π)² 2²11²π² 11²
r² = ---------- so, if C = 22π units, r² = -------------- = ---------------- = -------------
(2π)² (2π)^4 (2π)²(2π)² (2π)²
11²π²
or r² = ---------------
The area equation for a circle is A = πr² which here is π·11²/(2π)²
This reduces to 11²/{4π}
Make sure to multiply everything together, then check it with a calculater.
Hope this works:)
The answer is E because 12²
N = 4
(3)(4)-(2+4) = 12 - 6 = 6
