Question

Find the exact circumference of a circle with an area equal to 36 sq. in.

Answer 1

\[C=2\Pi R = 36 \]
From here,
R=5.73
Area=pi*r*r=>18*3.14=56.52 sq in.

Answer 2

Did you get it @mjenkins ?

Answer 3

i think you got your thingies criss-crossed @DLS

area = 36

find the circumference

Answer 4

oh lol ..sorry
Area=36
pi*r*r=36
r*r=11.14
r=3.38

C=2piR
=>2*3.14*3.38=21.26sq in.

Answer 5

thank you !

Answer 6

np!

Answer 7

exact values that use pi generally do not stop at 2 decies

Answer 8

but yes

A = pi r^2

sqrt(A/pi) = r

C = 2r pi

C = 2sqrt(A/pi) * pi

can one of you tell me how to ask another question ? lol
