4. find circumference of the following circle with radius 7cm.{ take =
)
7cm

43.96 cm²

Step-by-step explanation:

the circumfrece of a circle is either given by C= 2 x π x r or C = πd

r = radius

d= diameter(radius x2)

so that will be C = 2 x 3.14 x 7 or  3.14 x 7 = 43.96 cm²

π can be either 3.14 or 22/7
