Question

Find the exact circumference, in terms of , of a circle with the given radius.

x/2 miles

C = miles

Answer 1

in terms of pie

Answer 2

c = 2 Pi r

if r=x/2, then what do you thinnk c=?

Answer 3

x/4

Answer 4

no

Answer 5

2*pi*x/2=pi*x

Answer 6

2 times 3.14 times /2 = 3.14 times x

Answer 7

correct

Answer 8

soyour answer is 3.14x

Answer 9

yes or more precisely pi*x

Answer 10

Find the approximate value of the circumference of a circle with the given radius. Use = 3.14. Round your answer to the nearest tenth.

4 inches

C = inches

Answer 11

so if i use the formula you told me 2*pi*x/2=pi*x where would i substitute the 4 at

Answer 12

c= pi* 2r

Answer 13

c = 3.14x 2r would be 16 3.14x16

Answer 14

correct
