Question #116100

In a circle of radius 30 inches, a central angle of 35 will intersect the circle forming an arc of length _____.

Expert's answer

an arc of length = L"\\Delta"
R = 30 inches
"\\alpha" = 35°.

"L\\Delta=(\u03c0R\/180)*\\alpha",

"L\\Delta=(\u03c0*R\/180)*35=(\u03c0*30\/180)*35=35\u03c0\/6."
