Question

Usando o valor 3,14 para pi,calcule o comprimento da circunferência,cujo o raio mede


a) 6cm b)0,25

Answer 1

$\Large\boxed{\begin{array}{l}\rm a)~\sf C=2\cdot \pi\cdot r\\\sf C=2\cdot3,14\cdot6\\\sf C=37,68\,cm\\\rm b)~\sf C=2\cdot \pi\cdot r\\\sf C=2\cdot3,14\cdot0,25\\\sf C=1,57\,cm\end{array}}$

Answer 2

Explicação passo-a-passo:

$\mathsf{\pi=3{,}14;~r=6\,cm;~C=\,? }$

$\mathsf{C=2\cdot \pi\cdot r }$

$\mathsf{ C=2\cdot3{,}14\cdot6}$

$\boxed{\boxed{\mathsf{C=37{,}68\,cm}} }$

$\mathsf{\pi=3{,}14;~r=0{,}25\,cm;~C=\,? }$

$\mathsf{C=2\cdot\pi \cdot r}$

$\mathsf{C=2\cdot3{,}14\cdot0{,}25 }$

$\boxed{\boxed{ \mathsf{ C=1{,}57\,cm}}}$
