Explicação passo-a-passo:

$\blue{\tt obs :o\:diametro \: mede \: o \: dobro \: do \: raio \: }$

${ \boxed{ \tt \: </strong><strong>D</strong><strong> = </strong><strong>2</strong><strong>\times </strong><strong>r</strong><strong>}} \\ \tt \: r = 2</strong><strong>,</strong><strong>5m$

$\tt \: </strong><strong>D</strong><strong>= 2</strong><strong>,</strong><strong>5</strong><strong>m</strong><strong> \times 2 \\ \red{ \boxed{ \tt </strong><strong>D</strong><strong> = 5m}}$
