1. 1. The diameter of a right circular cylinder is equal to its altitude. Letting V and S be therespective volume and surface area of the cylinder and 2r the diameter, usedifferentials to estimate the maximum possible error, relative error, and percentageerror in computing(a) the volume of this cylinder and(b) the surface area of the cylinderwhen the measured diameter is 20 cm and the maximum possible error in themeasurement is 0.1 cm.

Prove that if semicircles are constructed on each of the sides of a right triangle, then the area of the semicircle on the hypotenuse is equal to the sum of the areas of the semicircles on the two legs.
Suppose that a company must service customers lying in an area of A square miles with n warehouses. Kolesar and Blum showed that when the warehouse(s) are located properly, the average distance between a warehouse and a customer is (????)12. Assume that it costs the company $90,000 per year to maintain a warehouse and $5,000,000 to build a warehouse. Also, assume that this $5,000,000 building cost is equivalent to incurring a cost of $500,000 per year indefinitely. The company fills 180,000 orders per year, and the shipping cost per order is $1.25 per mile. If the company serves an area of 120 square miles, how many warehouses (make it as an integer variable) should it have?

Use the marginal analysis criterion covered in class to find the number of units x that produces the minimum average total cost per unit in the given equation. C(x) = 0.001x3 + 7x + 250 x = units
You give a final attempt to bring the effect of Size back into the equation by forcing the assumption of homoskedasticity onto your estimation. The results are as follows: cost^= = 7,311.17 + 3,985.20 × Reputation – 0.20 × Size (1,985.17) (593.65) (0.07)+ 8,406.79 × Dpriv – 416.38 × Dlibart – 2,376.51 × Dreligion (1,423.59) (1,096.49) (989.23) R 2=0.72, SER = 3,682.02Calculate the t-statistic on the Size coefficient and perform the hypothesis test that its coefficient is zero. Is this test reliable? Explain.
A dietician prepares a diet specifying the amounts a patient should eat of the four basic food groups: group I, meats; group II, fruits and vegetables; group III, breads and starches; group IV, milk products. Amounts are given in "exchanges" that represent 1 oz (meat), 1/2 cup (fruits and vegetables), 1 slice (bread), 8 oz (milk), or other suitable measurements. Complete parts (a) through (c) below. (a) The number of "exchanges" for breakfast for each of the four food groups, respectively, are 2 , 1 , 2 , and 1 ; for lunch, 2 , 2 , 3 , and 1 ; and for dinner, 4 , 1 , 2 , and 1 . Write a 3 times 4 matrix using this information.
