Question

Help having trouble understanding which one is trueee.

Answer 1

Answer:

The value of π = 22/7 = 3.14

So here the Equation given we can examine those

1. 3π -1 > 9

=> (3 * 3.14 ) -1 > 9

=> 9.42 – 1 > 9

=> 8.42 > 9 , which is false

2. 7π > 21

=> (7 * 3.14) > 21

=> 21.98 > 21 , Which is true

3. π + 4 < 7

=> 3.14 + 4 <7

=> 7.14 <7 , Which is false

4. (12/ 4π) > 1

=> {12/ (4 * 3.14)} > 1

=> (12/12.56) > 1

=> 0.955 > 1 , Which is false
