Answer:
78.5cm^2
Step-by-step explanation:
Circumference equation = 2πr with radius r
10π = 2πr so r = 10π/2π = 5
Area of circle = πr^2
π * 5^2 = π * 25 = 25π = 78.53981... = 78.5 cm^2
So i would do this question is what is 4% of 49,839 and then think about it for a minute or so then if i got stuck i would type it into a claculator and what do you get 1993.56 would be your answer.
14 - 2n = -32
32 + 14 = 2n
46 = 2n
46/2 = n
23 = n
Checking:
14 - 2(23) = -32
14 - 46 = -32
-32 = -32 (Matched, answer is correct n = 23)
