Answer:
127 square ft
Explanation:
The formula to find the area of a circle with a know circumference is: C^2/4 π.
40^2 is 1600 and 4 times pi is 12.56. Divide 1600 by the 12.56 and you will get your area of 127.39. The answer is 127 square ft after rounding to the nearest square foot.
Answer:
an = 4n - 1
a1 = 3
a2 = 7 = 3 + 4
a3 = 11 = 3 + 4.2
a4 = 15 = 3 + 4.3
a5 = 19 = 3 + 4.5
.....
=> this is a arithmetic with a1 = 3 and d = 4
=> an = 3 + 4(n - 1) = 4n - 1
