Let me make a data firstly
Data:
diameter = 7 cm
required:
circumference=???
formula and solution:
circumference=2*pie*r (radius)
so here 2 and pie are constant values
but we dont have radius
for radius,
we have formula
r=d/2
substituting the value of d in above equation
r=7/2 =3.5 cm
now CIRCUMFERENCE =2*pie*r pie=3.14 , r=3.5
=2(3.14)(3.5)
21.98 or 22.00 (by rounding off ) ANSWER
