Question

If the circumference of a circular field is 6.28 feet, , what is the diameter of the field. Use 3.14 for Pi and do not round your answer

Answer 1

diameter = 2

Explanation:

circumference = 2rpi

6.28=2r(3.14)

6.28=6.28r

r=1

diameter = 2r

diameter = 2(1)

diameter = 2

Answer 2

✦ Given that

• The circumference is 6.28 ft

✦ We need to find

• The diameter of the field

Circumference formula:

`\longleftrightarrow \rm{C = \pi d}`

• 'C' is the circumference, 6.28 ft;
• 'π' is the number pi, 3.14;
• 'd' is the diameter, which is unknown

We plug in our values

`\longleftrightarrow\rm6.28=3.14d}`

`\longleftrightarrow\rm{2=d}`

Therefore the diameter of the circular field = 2 ft

`\underline{\rule{200pt}{4pt}}`
