Oh, this is for interactive activity at time 18:50...GREAT! But please kindly recheck your fist answer, im assuming you omitted x there, for (a)I assume you wanted to write h=340/((pie)(x^2)), That correct (c) For calculating value of x that will minimise should integrate substitution of your answer in (a) into surface area of cylinder, differentiating it and equating to zero, then solve for x, a different answer is thus possible, which is ranges between 0 and 3 cm, Kindly retry it
