Calculate the perimeter of a quarter circle 2mm use pi=3.14​

Step-by-step explanation:

If the radius of the circle is 2mm, the circumference is 4π mm.

Arc length of the quarter circle = π mm.

Perimeter of the quarter circle = arc length + 2 radii = 4π + 4 mm = 16.56 mm

f

step-by-step explanation:

f

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 %
