Circle Up Task Assessment
Geometric Standards
G-C.A: Understand and apply theorems about circles
G-C.B: Find arc lengths and areas of sectors of circles
The Library of Congress reading room has desks along arcs of concentric circles.
1. If an arc on the outermost circle with eight desks is about 12 meters long and makes of the circle, how far are these desks from the center of the circle? Draw this situation in the applet below. Be sure to include all calculations.
2. How many desks would fit along an arc with the same central angle, but that is half as far from the center? Draw this situation in the applet below. Be sure to include all calculations.
