Find the circumference and area of a circle with radius 7 m. Use the value 3.14 for pie, and do not round your answers

circumference (c) = 43.96cm

Area (A) = 615.44cm²

Step-by-step explanation:

Here,

Radious (r) = 7 cm

circumference (c) =

                            = 2×3.14×7

                            =43.96cm

Area (A) =

              = 4×3.14×7²

               =12.56×49

               = 615.44cm²
