Question

find the value of pi square correct to significant figures if 5 is equal to 3.14

Answer 1

Hello Friend,
Here,

π = 3.14

Here there are three significant figures. So, we will keep only three in our final answer.

π²
= π×π
= (3.14)×(3.14)
= 9.8596
= 9.86 (Rounding off)

So, π² = 9.86

Hope it helps.
