Question

Us Find the circumference of this circle ysing 3 for a C ~ [?] 20 C=πα

Answer 1

Answer:

C≈60

Step-by-step explanation:

remember circumference formula

$\displaystyle C = 2\pi r$

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

$\displaystyle C = 2\pi .10$

simplify mutilation:

$\displaystyle C = 20\pi$

substitute the given value of π:

$\displaystyle C = 20.3$

simplify multiplication:

$\displaystyle C = 60$

and we are done!

Answer 2

Answer:

$2*\pi *10=62.83185307$

$20/2 = 10$

$(Radius)$$Or the C = \pi*d$

62.83185307 is the answer
