Question

Find the diameter of a circle with a circumference of 443 feet. Use 3.14 for pi.

Answer 1

First we will find radius then multiply the radius by 2

Radius:

$\begin{gathered}\\ \sf ⇒443 = 2 \times 3.14 \times r\end{gathered}$

$\begin{gathered}\\ \sf ⇒443=6.28r \end{gathered}$

$\begin{gathered}\\ \sf ⇒r=70.5414 \end{gathered}$

Diameter:

$\begin{gathered}\\ \sf\longmapsto Diameter =2r\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto Diameter =2×70.5414\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto Diameter=141.0828\end{gathered}$
