Answer:

24.12

Explanation --

Circumference = Pi x D (d --> diameter)

Diameter = 2r (r --> radius)

4+4 (4[2]) = 8

3.14 times 8 (8 is the diameter we just found out, while 3.14 is pi) -->

25.12

Hope this helps!!

Answer:  c=πd

we need 'd'

hence,

d=2r

d=2(4cm)

d=8cm

now,

c=3.14×8cm

c=25.12cm
