What is the circumference of the circle?
The Circumference (or) perimeter of the circle = 2πR. where R is the radius of the circle.
The radius of the circle is;
[tex]\rm Radius=\dfrac{Diameter}{2}\\\\Radius=\dfrac{5}{2}\\\\Radius=2.5[/tex]
The bike move when you turn the pedals at an angle of 90 degrees is;
[tex]= \dfrac{90}{360} \times 2 \times 3.14 \times 2.5\\\\= \dfrac{1}{4} \times 2 \times 3.14 \times 2.5\\\\=3.9\\\\[/tex]
Hence. the bike is 3.9 feet far does the bike move when you turn the pedals at an angle of 90 degrees.
