Homework Help: Trigonometry

Posted by Anonymous on Monday, April 19, 2010 at 9:33pm.

Gabe is spending two weeks on an archaeological dig. He finds a fragment of a circular plate that his leader thinks may be valuable. The arc length of the fragment is about 1/6 the circumference of the original complete plate and measures 1.65 inches. A similar plate found earlier has a diameter of 3.14 inches.

Could Gabe's fragment match this plate?

How long would the arc length of a fragment be if it were 1/6 the circumference of the plate?

I have no idea how to start these.
