Question

Work out the circumference of this curcle. Give your answer in terms of pi and state its units​

Answer 1

:14pi and 43.98 (2dp)

Explanation:

circumference =2xpixr

radius = 14 divide by2 =7

2x pi x 7=14pi

14pi =43.98229715

=43.98 (2dp)

Explanation:

`Hey~There!`

_________________________

➜ First you need to set up the formula:

• Formula:
  `C=2`π
  `*r`

• 
  `2`π
  `*7=43.9822971503`

➜ Round:

• To round, look at the number in the tenths place:
  `9`. Now look to the right of that number, In this case it's an
  `8`. So if the number is greater than or equal to
  `5` then you round up. If it's less than

• So when we round
  `43.9822971503` we get:

- Thousandth:
`43.982`

- Hundredth:
`43.98`

- Tenth:
`44.0`

_________________________

So based on the above work we can conclude that the circumfrence of the circle is:

• Exact Form:
  `43.9822971503`

• Rounded Forms:
  `43.982`,
  `43.98`,
  `44.0`

• Whole Number Form:
  `44`
