The Greek letter $\pi$(pronounced as Pie) represents the ratio between the circumference and the diameter of a circle.

i.e. $\frac{circumferenceofthecircle}{Itsdiameter\left(d\right)}=\pi$

$=Circumferenceofthecircle=\pi \times d$

$=2.\pi .r$

Explanation

an isosceles triangle has equal in sides and in equal angle

Explanation

One trillion equals a thousand billion or million millions

1 trillion consists of 1 followed by 12 zeros,

that is, 1, 000, 000,000, 000

and can be written as \(10^{12} \) 

 It takes about 32,000 years to finish 1 trillion seconds.
