Question

If a circle has a radius of 2.7 meters, what is its circumference

rounded to the nearest meter?

Answer 1

17
`m^(2)`

Explanation:

The cirfumference of a circle when given the radius is 2πr

So pi is 3.14 thus:

2 × 3.14 × 2.7

16.956
`m^(2)`

When rounding of to the nearest meter check if the number in the tenths side is bigger than 5. It is bigger so we add 1 to the units making it 17
`m^(2)`.

Answer 2

17 meters

Explanation:

the circumference is solved by multiplying the diameter by pi.

the diameter can be found by multiplying the raduis by 2

the diameter is 5.4

5.4 x 3.14

16.956

about 17 meters
