Answer:
25.5ft to the nearest tenth
Step-by-step explanation:
The question above is answered below.
Circumference of a circle is measured by 2pieR; that is:
[tex]c = 2 \: \pi \: r[/tex]
where, pie = 22/7
Since we are to get the value of radius, we make r subject of the formula above.
Recall
[tex]c = 2 \: \pi \: r \\ make \: r \: subject \: of \: formula \: by \: dividing \: through \: by \: 2\pi \\ \frac{c}{2\pi} = \frac{2 \: \pi \: r}{2\pi} \\ \\ r = \frac{c}{2\pi} [/tex]
Where,
C = 160ft; pie = 22/7
Thus,
[tex]r = \frac{160}{2 \times \frac{22}{7} } ft[/tex]
[tex]r = \frac{160 }{ \frac{44}{7} } ft[/tex]
[tex]r = \frac{160}{6.2857} ft[/tex]
[tex]r = 25.45 \: ft[/tex]
[tex]r = 25.5 ft \: \: to \: the \: nearest \: tenth[/tex]
