Question

find the radius of a circle whose circumference is 3.14 centimeters

Answer 1

Hey here's your answer!

Circumference = 2*pi*r

3.14 = 2*3.14*r

2r = 1

r = 1/2 = 0.5 cm

Radius is 0.5 cm.

Hope this helps! :)

Answer 2

Circumference: 3.14cm

Since we know that the formula for circumference is 2 × π × radius, substitute the given values into the formula.

2 × π × radius = 3.14

Move the 2 over to 3.14 and divide.

π × radius = 3.14 ÷ 2

π × radius = 1.57

To find the radius, divide 1.57 by π. (π = 3.14)

1.57 ÷ 3.14 = 0.5

Therefore, the radius of the circle is 0.5cm.
