Question

Is it true or false that the circumference of a circle is about 3 times long as the radius?

Answer 1

False

Step-by-step explanation:The circumference of a circle is approximately three times its diameter. If you divide the circumference by its diameter, the constant ratio is called Pi, which is an irrational number shown with this symbol: For example, the circle below has a radius of 4.5 inches.

Answer 2

False

Explanation:

Circumference = 2πr

= 2 * 22/7 * r

= 44/7 * r

≈ 6.28 * r

Therefore, the circumference is approximately 6.28 times the radius
