120πcm²

Step-by-step explanation:

Since we are keeping this in terms of pi, you do not necessarily need a calculator. I will be doing my calculations as simple as I can.

First we need to figure out the area of the top circle and bottom circle.

We know that the formula for the area of a circle is:

πr²

So we need both circles, our formula becomes:

2πr²

Let's substite our radius in.

2 × π × 4² = 32πcm²

Now we need to find the area of the sides itself. Our formula here is:

2 × π × r × h

Let's substitute our radius and height in:

2 × π × 4 × 11 = 88πcm²

Let's now add both of these together:

88πcm² + 32πcm² = 120cm²

Remember to add your measurements!

Hope this helped!

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
