Area of a circle;
A = C²/4π
A = 12²/4π
A = 144/4π
A = 36/π
A ≈ 11.46
hope this helps, God bless!
864/12 = the rate per hour, which would be 72 mph. To find how many miles she would drive at the same rate, multiply the 72 (miles) with 9 (hours) which is equal to 648 miles
The answer is 24 : 12 x 1 / cos60 = 24
Now, the average cost per night is 495....for 5 nights, it is (495 * 5) = 2475
and since the cost has tripled in the past 4 years....we can divide the regular cost by 3 to find out how much it would have cost 4 years ago
2475/3 = 825..thats for a 5 night stay 4 yrs ago
so the difference is : 2475 - 825 = 1650
