Question

The circumference of a circle is 25.12 centimeters. What is the circle's diameter? than it says Use 3.14 for ​. I WILL MARK U AS BRAINLIEST

Answer 1

Solution

Circumference of a circle = 25.12cm

= 2πr = 25.12

= πr = 25.12/2 = 12.56

= r = 12.56/3.14 = 4

Answer 2

${\green{Circumference\:of\: circle = 2πr }}$

25.12 cm = 2× 22/7 × r

25.12cm/2 = 22/7 × r

12.56 = 22/7 × r

12.56 × 7/22 = r

1256/100 × 7/22 = r

8792/2200 = r

1074/275cm = r

diameter = radius × 2

= 1074/275cm× 2

= 2148/275cm

$\boxed{\underline{\red{\bf{ Answer : \frac{2148}{275}cm }}}}$
