A. multiply the two numbers together to get your answer. so your answer is 15 different combos.
B. Same with a, you multiply all the numbers. 2x3x5=30. 30 different combos

Part 1: Circumference of circle = inches & Area of circle =
Part 2: Area of circle =
Part 3: Area of square not covered by circle = .
<u>Step-by-step explanation:</u>
<u>Part 1:</u>
We have radius of circle as . Let's find area & circumference of circle:
Circumference of circle =
⇒ Circumference of circle =
⇒ Circumference of circle = =
⇒ Circumference of circle = inches
Area of circle =
⇒ Area of circle=
⇒Area of circle = =
⇒ Area of circle =
<u>Part 2:</u>
Circumference of circle = =
⇒
⇒
Area of circle =
⇒Area of circle = =
⇒ Area of circle =
<u>Part 3:</u>
Perimeter of square = , a is side of square.
⇒
⇒
⇒ a =
Since radius of circle inscribed in square is half of side of square i.e.
Now, Area of square not covered by circle = Area of square - area of circle
⇒
⇒
⇒
∴ Area of square not covered by circle = .

Answer:
1 -4i
Step-by-step explanation:
1-sqrt(-16)
We know that sqrt(ab) = sqrt(a) sqrt(b)
1 - sqrt(16) sqrt(-1)
Assuming we take the principal value of the square root
The square root of -1 is i
1 -4i
