The diameter of a circle is 4 in. Find its area in terms of π\pi π.

If the diameter of the circle is 4 in. then the radius of the circle is 2

the formula for the circle area is

A = πr^2

r = radius

A = π * 2 * 2

A = 12.57 if solved

Step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
