Question

can anybody help me on some circles and pi

Answer 1

@triciaal

Answer 2

post the full problem please

Answer 3

ok

Answer 4

find the circumference of the circle to the nearest foot

Answer 5

the diameter of this circle is 42 ft?

Answer 6

yep

Answer 7

you will use the formula

C = pi*d

C = circumference
pi = 3.14 approximately
d = diameter

Answer 8

alternatively you can use

C = 2*pi*r

r = radius

but 2*r = d so it's easier to use the first version

Answer 9

look im no math genius like you can you say that in a better understanding way ... :)

Answer 10

you take pi and the diameter and multiply them

"pi" is just a number

pi = 3.14 approximately

Answer 11

so you're just going to do 3.14 times the diameter to get the circumference

Answer 12

3.14 x ??? im sorry im really stupid and bad at math whats the diameter?

Answer 13

42 like you said above

Answer 14

ohh

Answer 15

131.88

Answer 16

then you round to the nearest whole number

Answer 17

since they say "to the nearest foot"

Answer 18

130

Answer 19

132 actually

131.88 is closest to 132

Answer 20

oh

Answer 21

so the answer is 132

take the diameter and cut it in half to get the radius

Answer 30

so 4

Answer 31

correct

pi = 3.14 approximately
r = radius

Answer 37

the * means multiply

Answer 38

3.14 * 2* r right?

Answer 39

yes

Answer 40

replace r with the radius

the radius in this case is 2.5

Answer 41

so 15.7

Answer 42

yes

Answer 43
