Answer:

C≈60

Step-by-step explanation:

remember circumference formula

[tex] \displaystyle C = 2\pi r[/tex]

given that,d=20 therefore r would be 20/2=10 thus substitute:

[tex] \displaystyle C = 2\pi .10[/tex]

simplify mutilation:

[tex] \displaystyle C = 20\pi [/tex]

substitute the given value of π:

[tex] \displaystyle C = 20.3[/tex]

simplify multiplication:

[tex] \displaystyle C = 60[/tex]

and we are done!
