Calculate. thee. volume. of a. cylindrical. steel by which is 8 cm long and 3.5 cm in diameter

308cm³

Step-by-step explanation:

volume of cylinder = πr²h

volume = (22/7)*(7/2)*(7/2)*8

volume = 308cm³

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 %  

step-by-step explanation:

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
