Answer:
6.28 cm
Step-by-step explanation:
The formula for the circumference of a circle with radius r is C = 2*pi*r.
If we let pi = 3.14 and r = 1 cm, then the circumference of this circle is
C = 2(3.14)(1 cm) = 6.28 cm
Answer with explanation:
It is given that for three integers , a, b and c, if
Since , a b is divisible by c , following are the possibilities
1.→ a and b are prime integers .Then , c will be prime number either equal to a or b.
2.→a and b are not prime integers ,then any of the factors of a or b will be equal to c.For example:
⇒a=m × n
b=p × q× c
or,
⇒a=u×v×c
b=s×t
So, whatever the integral values taken by a, and b, if 
then either of 
is true.
Answer:
Step-by-step explanation:
Given that X - the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.
Height of male pilot = 74.2 inches
We have to find the percentile
X = 74.2
Corresponding Z score = 74.2-72.6 = 1.6
P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%
i.e. only 5% are below him in height.
Thus the malepilot is in 5th percentile.
K = y/x OR y = kx
