Answer 2

\[\huge 22=2 \times \frac{22}{7} \times r\]
find the value of r???

Answer 3

Hold on, (:

Answer 4

C = 2*pi*r C = 22

22/2 pi = r

11 pi = r

A= pi*r^2

A = pi* (11 pi)^2

A = pi * 121/pi^2

A= ?

Answer 5

sure.. @atrabilious

Answer 6

Oh no my answer isn't right at all.

Answer 7

lmao \[\huge 22 = 2 \pi r \therefore r = 22/2\pi = 11 \pi\]

Answer 8

38.52 ?

Answer 9

ok...i give you hint:
\[\huge r=\frac{22 \times 7}{2 \times 22}\]
can you solve it?? @atrabilious
