ide a certain radius. Josh budgets $200 per year for oil changes on his vehicle. He lives 7 miles outside the radius. What is the greatest number of oil changes (c) that he can schedule and keep on budget for the year?
1) x² + y² = 64 is the EQUAION of a cercle with a radius R = √64 =8
2) The cross section is a triangle with H = BASE. Since R = 8 that means the Base B= 16 and also the height H =16 This solid is then a regular cone and its Volume value is V = πR².H V π(8)².(16) = 2014π units³ or ≈ 3217 units³
