Answer 1

The radius of a circular field is 70 metres.

Calculate it's circumference.

${{\rm{C=2 \pi r}}} \\ {{\rm{C=2 \times 3.14 \times 70meters}}} \\ {{\rm{C = 6.28 \times 70}}} \\ \boxed{\begin{array}{}{{\rm\red{\implies \: 439.6meters}}}\end{array}}$

Answer 2

Answer: 439.82

Step-by-step explanation:

C=2πr=2·π·70≈439.82297
