Arc length: Because the Earth is essentially circular. West Seattle 47.6 o latitude by ~-123 o longitude Grants Pass 42.4 o latitude by ~-123 o longitude Earth radius is ~3963 miles. West Seattle 47.6 o latitude by ~-123 o longitude Grants Pass 42.4 o latitude by ~-123 o longitude Earth radius is ~3963 miles.

Area of a Sector Where we answer the question: How many square inches is 1/9 of the pizza?

Linear and Angular Velocity Bugs on a record

How Fast are WE traveling … Grants Pass In radians per hour? In miles per hour? Note: because r = 3,963 miles and the angles given…. x = 2,945 miles
