Question

Help me someone please my teacher needs this soon or I’m going to fail school

Answer 1

• Radius=3in

`\\ \sf\longmapsto Circumference=2\pi r`

`\\ \sf\longmapsto Circumference=2(3)(π)=6\pi`

Now

Check 1st option

`\\ \sf\longmapsto (9\pi)/(3).2=6\pi`

Answer 2

• A. 9π/3 · 2

Explanation:

Use the equation of circumference and substitute the value of radius:

• C = 2πr

• C = 2π*3 = 6π inches

Compare the answer choices to find the correct one, which is:

• 9π/3 · 2 = 3π · 2 = 6π
