Question

Qual é a distancia percorrida a cada volta do pneu com diâmetro de 50 cm?

Answer 1

C=π*d
C=3,14*50
C=157
Resposta: 157cm (1,57m)

Answer 2

$\Large\displaystyle\begin{gathered} \sf{C=\pi\cdot d } \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \sf{C=3{,}14\cdot50 } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\sf{ C=157\,cm}} \end{gathered} }$
