Let your learners discover the general formulae for the area of a sector and arc length with this worksheet.
Here students are asked to fill in the blanks to find the area of various sectors, from a quarter to an angle of 60°, any sized angle and finally, a general formula with any sized angle and radius length.
This process is repeated for arc length, starting with a quarter circle and ending with a general formula.
Practice using these formulae next with the “Area of Sectors and Arc Lengths” worksheet.
