Answer:
6.28 cm
Step-by-step explanation:
Given,
Diameter = 2 cm
pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 2 / 2
= 1 cm
Formula : -
Circumference ( circle ) = 2 pi r
2 pi 4
= 2 × 3.14 × 1
= 6.28 cm
The answer is No
Don't forget put heart ♥️
x^2-2=7
Subtract 7 from both sides
x^2-2-7=7-7
x^2-9=0
x^2-3^2=0
Using a^2-b^2=(a+b)(a-b)
Where a=x and b=3
(x-3)(x+3)
