The circumference is a circle is 8pie. What is the diameter of the circle?

C = pi•d

We are given that C = 8pi.

8pi = pi•d

8pi ÷ pi = d

8 = d

The diameter is 8.

D = 8

Step-by-step explanation:

Circumference equals 2 × π × radius

Diameter equals 2 × radius

Diameter = Circumference/π

8π/π = 8

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
