Question

What’s the area of the shaded region?

Answer 1

217.04 cm²

Explanation:

We should first calculate the area of the rectangle:

A= 14*21 =294cm²

then we should substract the area of the half-cercle :

A'= (7²*π)/2=76.96 cm²

then the area of the shaded area is :

A"= 294-76.96= 217.04 cm²
