Answer 1

Answer:

61.6cm²

Step-by-step explanation:

we have length of the pendulum is 14cm and angle substended by pendulum is 18 degree......

so path covered by pendulum is...

as,formula is....

$angle \: substended \div 360 \times 2\pi \times r ^{2}$

so, = 18/360×2×22/7×14²

= 44×14/10

=616/10

=61.6cm²

So, the area or path covered by the pendulum is 61.6cm².
