Below are sample questions representative of the exercises included on this worksheet and related GEO.182 Communicate a model with diagrams, equations, and reasoning skill assessments:

Problem 1Difficulty: Mastery

A glass roof panel is modeled as an isosceles trapezoid with bases 18 feet and 10 feet and height 6 feet. Which final report statement best communicates the area and why the slanted sides are not needed?

AThe bases are 18 ft and 10 ft, so A = 18(10) = 180 square feet; the height is not needed.

BThe height is 6 ft, so A = 6² = 36 square feet; the bases are not needed.

CThe slanted sides are most important, so A = 2(18 + 10 + 6) = 68 square feet.

DThe bases are parallel and the perpendicular height is 6 ft, so A = 1/2(18 + 10)(6) = 84 square feet; the slanted sides are not needed for area.

Solution & Explanation:Trapezoid area uses the two bases and the perpendicular height. The clear statement identifies the needed measurements, computes 84 square feet, and explains why slanted sides do not determine area.

Problem 2Difficulty: Mastery

A circle has a diameter with endpoints (2,-1) and (10,5). Which equation best communicates the circle model?

AThe center is (8,4), the radius is 10, and the equation is (x - 8)² + (y - 4)² = 100.

BThe center is (6,2), the radius is 10, and the equation is (x - 6)² + (y - 2)² = 100.

CThe center is (6,2), the radius is 5, and the equation is (x - 6)² + (y - 2)² = 25.

DThe center is (2,-1), the radius is 5, and the equation is (x - 2)² + (y + 1)² = 25.

Solution & Explanation:The center is the midpoint of the diameter endpoints, (6,2). The diameter length is 10, so the radius is 5 and r² = 25.

Problem 3Difficulty: Mastery

A triangle has sides 7 units and 10 units with an included angle of 60 degrees. A student writes c² = 7² + 10². Which critique best communicates the problem with the model?

AThe Pythagorean theorem works for every triangle, so c = sqrt149 units.

BThe Pythagorean theorem needs a right angle; with included angle 60 degrees, use c² = 7² + 10² - 2(7)(10)cos 60 degrees, so c = sqrt79 units.

CThe included angle should be added to the sides, so c = 77 units.

DThe side c must be 7 + 10 = 17 units because all triangle sides add.

Solution & Explanation:The original model assumes a right angle that is not given. The Law of Cosines uses the included 60-degree angle and gives c² = 79.
