A homeowner wants to build a fence to 1. least cost = $120 enclose a 180 square yard rectangular area in his backyard. Along one side the fence is to be O 2. least cost = $125 made of heavy-duty material costing $9 per yard, while the material along the remaining 3. least cost = $110 three sides costs $1 per yard. Determine the least cost to the homeowner. 4. least cost = $130 5. least cost = $115A sphere of radius r is centered at the ori- 2024 gin. A right circular cone is inscribed in the 1. max vol = 3 -7 cu. ins. sphere as shown in the figure (0, r) 2. max vol = 2048 -7 cu. ins. 3 3. max vol = 2042 3 - cu. ins. y 4. max vol = 2030 -7 cu. ins. (x, - y) X 3 Find the largest volume the cone can have 5. max vol = 2036 3 -7 cu. ins. when r = 12 inches
