Alex needs to buy compressed air to fill empty cylindrical tanks for his tire store. each tank is 12 feet deep and has a radius of 6 feet. what is the volume of compressed air needed to fill 5 tanks? (use 3.14 for π.) (1 point)

Formula

Volume = πr²h


Find Volume of one tank

Volume of 1 tank = πr²h
Volume of 1 tank = 3.14 x 6² x 12
Volume of 1 tank = 678.24 ft³


Find Volume of 5 tanks

Volume of 1 tank = 678.24
Volume of 5 tanks = 678.24 x 5 
Volume of 5 tanks = 3391.2 ft³


3391.2 ft³

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
