Answer:
<h2>1. A = 78.5 in²
</h2><h2>2. C = 31.4 in
</h2>
Step-by-step explanation
1. area of a circle = πr²
2. circumference of a circle = 2πr
where diameter = 10 in.
radius = 10 / 2 = 5 in
1. area of a circle = π(5)²
= 78.5 in²
2. circumference of a circle = 2πr
= 2π(5)
= 31.4 in
Area of circle= πr² so, our radius would be 5in because the diameter is 10 in which makes our sum to be π×5²= 7 8 . 5 in
Circumference of circle= 2πr so, 2×5×π= 3 1 . 4 in

Answer:
$187.46
Step-by-step explanation:
156.22 x .2 = 31.244
So she left $31.24(4) as a tip, so if we add that to $156.22 then you get the total cost.
156.22 + 31.244 = 187.464
$187.46
