Karissa made a giant circular sugar cookie for dessert. She wants to frost it. The cookie has a 14 inch diameter. How many square inches of frosting are needed to cover the entire top of the cookie?

153.86in^2

Step-by-step explanation:

Area of a circle = πr²

Where : = π = pi = 3.14

R = radius = 14/2 = 7

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

7² x 3.14 = 153.86

A radius is half of the diameter

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

7

step-by-step explanation:

the answer would be 7
