Answer: A = 74.2 in²
Step-by-step explanation:
θ = 105(π/180) = 21π/36 radians
A = (θ/2)R²
A = ½(21π/36)9²
A = 74.22012...
Answer:
$32.39
Step-by-step explanation:
She has a 15-gallon tank and it has 1/5 a tank of gas left (so about 3/15)
Because she needs to refill it and already has 1/5, she'll only need to pay for 4/5 a tank of gas (12/15).
So the equation should be 12 times $2.699.
12 × 2.699 = 32.388
Then, round to the nearest cent.
32.388 = $32.39
