okay so I already got the work but I dont know what the fina

c 67 d-146v 146 Grace\'s bakery specializes in giant cupcakes. Each cardboard cupcake container is filled with batter and baked in the oven. The baked cupeake forms a perfect hemispherical on top of the container. The surface area of this is frosted. A clear plastic lid, identical in size and shape to the cupcake container, is then placed on top. These containers are designed such that R.- R, and h = 2 R. Given that 100 cmr\' of batter costs 9e, 100 cm2 of frosting costs 27e, 100 cm2 of cardboard costs 1.5e, and 100 cm2 of plastic costs 3e, complete the tasks below on the next page. The following formulas may be helpful: Conical frustum: Hemisphere SA=2ar\' SA (sides only)s (R, + R)s a. Create functions of R, which return the cost, in dollars, of ingredients, I, and packaging. P. Approximate all coefficients to 4 decimal places. ingredients. Round to 2 decimal places Hints: Consider that =. Use the intersect, graphing calculator tool to find R b. Find the volume ofa baked cupcake if Grace wants 85% of the cost to go toward 85 P 15 p15 c. Find the efficiency ratio for the packaging to the baked cupcake, to 2 decimal places. 38

Solution

l = 37 / 150 pi R³₁

P = 25.78 pi R²₁ / 100

Ratio = Cost of cup cake / P

By summing the total cost of Cake in cup and the hemisphere part, we get the cost of cake and then divideit with P, you will get the answer
