Question 1180922

A sector of a circle has an arc length of π cm and a central angle of π/6 radians. What is the area of the sector?
<pre>This is WRONG ====> The sector area is {{{(1/2)pi*6^2}}}.
Correct answer: With radius = 6, {{{highlight_green(matrix(1,17, Area, of, sector , "=", 1/12, "*", pi*r^2, "=", 1/12, "*", pi*6^2, "=", 1/12, "*", 36pi, "=", highlight(3pi)))}}}
