Question

Find the circumference of this circle using 3 for T. C~[?] 15 C = 27Tr

Answer 1

Answer: 90

Step-by-step explanation:

c = 2πr

r = 15

d = 30

30π = 90

Answer 2

Answer:

C≈90

Step-by-step explanation:

remember circumference formula

$\displaystyle C = 2\pi r$

given that,r=15 thus substitute:

$\displaystyle C = 2\pi .15$

simplify mutilation:

$\displaystyle C = 30\pi$

substitute the given value of π:

$\displaystyle C = 30.3$

simplify multiplication:

$\displaystyle C = 90$

and we are done!
