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:

K=1/2bc sinA

K=1/2ab sinC

K=1/2ab sinB

K=1/2a^2 sinBsinC/sinA

K=1/2b^2 sinAsinC/sinB

K=1/2c^2 sinAsinB/sinC

Heroes 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 theradius of the circle.

Find the area of a sector given the measure of the corresponding central angle and the radiusof the circle.

Write a problem for each topic, including all information needed to solve the problem, including adiagram. Then write the solution to the problem, showing all the steps needed to find the solution,including the formula. Include a sentence that describes the solution based on the original problem.

(If possible to be done in a world document would be amazing, thanks)
