Question

The radius of a circle is 14 centimeters. What is the circle's circumference?

Answer 1

Hello!

To solve this exercise, we must use the formula below:

`\mathrm{C=2\cdot\pi\cdot r}`

• C = ?
• π = 3.14
• r = 14cm

Knowing these values, let's replace them in the formula to obtain r:

`\mathrm{C=2\cdot 3.14 \cdot 14}\\\mathrm{C=6.28 \cdot 14}\\\\\boxed{\mathrm{C=87.92}}`

So, the circle's circumference is 87.92cm.

Hope this helps!

Answer 2

• 
  `\boxed{\sf{87.92cm}}`

Explanation:

To solve this problem, you need to multiply the radius of a circle by the circumference formula.

Circumference formula:

`\sf{C=2\pi r}`

`\sf{C=2*\pi r}`

C=?

π= 3.14

r= 14

`\sf{2*3.14*14}`

Solve.

`\sf{2*3.14=6.28}`

`\sf{6.28*14=\boxed{\sf{87.92}}`

• Therefore, the correct answer is 87.92cm.
