Homework Statement
Three mutually tangent circles with the same radius r enclose a shaded area of 24 square units. Determine the value of r to the nearest unit.
Homework Equations
do i use the arc length formula to find the answer?
3. The Attempt at a Solution
A=(central angle*pi*r^2)/360
the central angle is 60 because if u draw a triangle between the three centers of the circles it is equilateral...but i don't know how to get r with only this information
