Find the diameter of a circle whose circumference is 25.

                                                     

║⊕ANSWER⊕║

GIVEN

Circumference of the circle = 25

=> 2πr = 25

=> 2 * 3.14 * r = 25

=> 6.28 * r = 25

=> r = 3.9 cm

Since, Diameter = 2 * radius,

The diameter of the circle is 7.8 cm

                                                   

Answer 2

Answer:

7.95774716

Step-by-step explanation:

WK, circumference of circle=2πr

25=2πr

25=2πrr=25÷2π

25=2πrr=25÷2πr=7.95774716

where r is radius of circle.
