Question

circumference if diameter is hundred centimetre​

Answer 1

GIVEN THAT

• The diameter of the circle is 100 cm

TO FIND

• Circumference of the circle

FORMULA USED

• Circumference of circle = 2 × π × r

SOLUTION

We know, radius of circle = d / 2

= 100 / 2 = 50 cm

So, the radius of the circle is 50 cm

NOW,

= 2 × 22 × 50

7

= 314.28 cm
