A square has an area of 40cm³ work out the circumference of the circle.

please help need it ASAP

The circumference of the circle is approximately 19.8 centimetres.

Step-by-step explanation:

If the square has an area of 40 square centimetres, that means that the side length of the square is √40, or 2√10

The side length will be the diameter of the circle. Which is all we need to find its circumference.  The circumference of a circle is equal to pi times its diameter, so we say:

c = πd

c = 3.14 × 2√10

c = 6.28√10

c = 6.28 × 3.16

c = 19.8

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857
