The circumference of a circle is 8.97cm.

wlad13 [49]

The length of the diameter is 2.86 cm rounded to 2 DP

Step-by-step explanation:

The formula of the circumference of a circle is

C = 2πr, where r is the radius of the circle
C = πd, where d is the diameter of the circle

∵ The circumference of a circle is 8.97 cm

- We need to find the diameter of the circle, then we will use

the 2nd formula of circumference above

∵ The circumference = πd

- Substitute the value of the circumference in the formula

∴ 8.97 = πd

- Subtract both sides by π

∴ 2.855 = d

- Round it to 2 decimal places (to the nearest hundredth)

∴ d = 2.86 cm

The length of the diameter is 2.86 cm rounded to 2 DP
