Answer 1

is the answer approx 32?

Answer 2

how did you work the problem

Answer 3

ok, firstly a circle has 360 degrees

Answer 4

so you need to multiply 14 by 360/25

Answer 5

got it?

Answer 6

to find a circumference

Answer 7

we are supposed to leave pi in the answer

Answer 8

circumference=2*pi*r

Answer 9

so the circumference=14*360/25=2*pi*r

Answer 10

so by this i found r

Answer 11

so 201.6=2pi*r

Answer 12

yes

Answer 13

then divide by 2pi? i keep getting 100.8pi but it says its the wrong answer

Answer 14

ok i got it i had to put32.1
THanks!
