Question

Find the circumference and area of a circle in terms of pi. Will medal and fan for help.

Answer 1

d = 15m

Answer 2

Is there a pic?

Answer 3

nope, that is all the information i have.

Answer 4

ok well the formula for a circle is C=2πr

Answer 5

But since its diameter you just divide the diameter

Answer 6

so it would be C=2π7.5

Answer 7

Which equals 47.1

Answer 8

That should be your answer

Answer 9

I am confused... where did you get the radius?

Answer 10

The radius is half of the diameter

Answer 11

\[7.5\times2=15\]

Answer 12

and shouldn't the equation be \[C=\pi*d\]

Answer 13

When you just have the diameter you just divide it by 2 to get the radius

Answer 14

Nope the formula Is C=2πr

Answer 15

The radius is half of the diameter

Answer 16

Your problem gave us the diameter so to find the radius we needed to divide the diameter by 2

Answer 17

Giving us 7.5 since the diameter is 15

Answer 18

okay...

Answer 19

Are you still confused?

Answer 20

yeah... but math is always confusing

Answer 21

lol i can break it down further
