Answer» ong>Answer: RADIUS of circular sheet(R)=14cm and Radius of SMALLER circle(r)=3.5cm Length of rectangle(l)=3cm and breadth of rectangle(b)=1cm According to question, Area of remaining sheet=Area of circular sheet−[Area of two smaller circle+Area of rectangle] =πR −[2(πr 2 )+(l×b)] = 7 22
×14×14−[(2× 7 22
×3.5×3.5)−(3×1)] =22×14×2−[44×0.5×3.5+3] =616−80 =536cm 2
Therefore the area of remaining sheet is 536cm 2 . MARK me as brainliest |
