# How to find the area of gray portion in the image ?

To find the area of gray portion, we use the below equation

Area of gray portion = Area of the semicircle on the Left hand side – Area of semicircle with diameter 2.6 cm + Area of semicircle with diameter 1.8 cm

=> 0.5 * π[0.5*(2.6+1.8)]^2 – 0.5*π(1.3)^2 + 0.5*π(0.9)^2

=> **6.22035345411****sq cms**

Hope that helps !!
