exact TT
12
C = [?]
C=πd

Answer 1

Answer:

Solution given;

diameter[d]=12

we

have

circumference of circle=πd=12π

12 is a required answer.

Answer 2

☞ Question:

• π is an unending decimal. Find the circumference of the circle below using exact π.

☞ Formula for Circumference:

• $\boxed{C = πd}$

☞ Formula for Pie (π):

• $\boxed{π = \frac{22}{7} \: \: or \: \: 3.14}$

☞ Given:

• π = 3.14
• d = 12

☞ Let's try!

• $C = πd$
• $C = (π)12$
• $C = (3.14)12$
• $\boxed{C = 37.68}$

☞ Answer:

• $\huge\boxed{C = 37.68}$
