Assignment: Area and Length Suppose you and a friend are studying for an exam about the topics in this section. The two of you decide to create a practice guide on how to solve these types of problems. Write a practice guide by writing one problem for each of these three topics:  Find the area of a triangle using one of the following formulas: 1 bc sin A 2 1 K = ab sin C 2 K= K= 1 ac sin B 2 K= 1 2 sin B sin C a 2 sin A 1 2 sin A sin C b 2 sin B 1 2 sin A sin B K= c 2 sin C K= Hero’s Formula: K =   s ( s − a )( s − b )( s − c ) Find the arc length of an arc given the measure of the corresponding central angle and the radius of the circle. Find the area of a sector given the measure of the corresponding central angle and the radius of the circle. Write a problem for each topic, including all information needed to solve the problem. Then write the solution to the problem, showing all the steps needed to find the solution. Include a sentence that describes the solution based on the original problem. © K12 Inc. © K12 Inc.
