Um cortador de grama elétrico tem o cabo plugado em uma tom

Um cortador de grama elétrico tem o cabo plugado em uma tomada fixa rente ao solo plano de um gramado. O cabo de energia mede 5 metros, e o cortador tem uma lâmina que corta 1 metro de largura. Atualmente ele corta, portanto, uma região no formato de círculo de raio 6 m, como ilustra a figura. Pretende-se usar adicionalmente um cabo extensor, de modo que seja possível cortar uma região com o dobro da área que corta atualmente.

Qual a medida aproximada, em metro, do comprimento do cabo extensor?
