The radius of a sphere is 3 inches. Which represents the volume of the sphere?

12(pi)cubic inches
36(pi)cubic inches
64(pi)cubic inches
81(pi) cubic inches

36 (pi) cubic inches.

Step-by-step explanation:

Recall that the formula for the volume of a sphere is 4/3 times pi times the radius cubed. Knowing what our radius is, we can simply find the volume.

First, lets make the radius cubed.

So, 3 times 3 times 3 is 27.

Alright, we cubed our radius, so lets multiply that with 4/3.

4/3 times 27 is 108/3 or 36.

Now that we have 36, we can simply just put 36 and pi together to get the exact answer instead of changing pi to 3.14 or another approximate.

Hope this helps!

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 %
