circumference of a circle

Answer:
Diameter of the circle = 8.99 units
Step-by-step explanation:
in order to find the diameter of the circle whose circumference is 28.26 units
we will adopt the formular for finding the circumference of a circle
circumfrence of a circle = π × diameter of the circle
given,
circumference of a circle = 28 . 26 units
π = 3.142
diameter of the circle = ?
28.26 = 3.142 × D
28.26 = 3.142D
divide both sides by 3.142
28.26/ 3.142 = 3.142D/3.142
8.99 = D
D = 8.99 units
therefore the Diameter of a circle whose circumference is 28.26units is evaluated to be 8.99 units
