Answer:
(b) 36.56 ft
Step-by-step explanation:
The perimeter is the total of the circumference of a 4 ft circle and two lengths that are 12 ft.
The circumference is given by ...
C = πd
C = (3.14)(4 ft) = 12.56 ft
Adding the 24 ft of straight sections, we find the total perimeter to be ...
P = 12 + 12 + 12.56 = 36.56 . . . feet

Answer:
E. 10 and 10
Step-by-step explanation:
Standard Deviation is the square root of sum of square of the distance of observation from the mean.
where, 
is mean of the distribution.
Here, since standard deviation is the ratio of the distance from the mean and sample size. So for decreasing the standard deviation we should keep numerator constant and increasing the denominator.
This can be only possible in option (E).
Hence, only Option (E) is correct.
It could be 2.5+2.5=5 and then add that to 4 and that equals 9
