Question

in the given figure angle aob is a straight line if angle aoc is equal to 3x + 10 degrees and angle boc 4x - 26 degrees then find the value of x​

Answer 1

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]

=πR2−[2(πr2)+(l×b)]

=722×14×14−[(2×722×3.5×3.5)−(3×1)]

=22×14×2−[44×0.5×3.5+3]

=616−80

=536cm2

Therefore the area of remaining sheet is 536cm2.
