Answer:
1. 23.55 in
2. 102.36 mm
Step-by-step explanation:
First, the circumference of a circle is written as: [tex]C=\pi d=2\pi r[/tex], where either equivalence works and d = diameter and r = radius.
1. We know that d = 7.5, so we just plug this into the equation:
[tex]C=\pi *7.5=3.14*7.5=23.55[/tex]
Thus, the circumference is 23.55 inches.
2. We know here that r = 16.3, so we can plug this into the other equivalence:
[tex]C=2*\pi *16.3=2*3.14*16.3=102.364[/tex] ≈ [tex]102.36[/tex]
Thus, the circumference is 102.36 millimeters.
Hope this helps!
