Question

Use pi = 3.14 to estimate the circumference of the circle to the nearest hundredth.

middle of circle is 11cm

Answer 1

69.115cm you would do 11 times to then you get 22 and do 22 times pi and get 69.115

Answer 2

Circumference of the circle to the nearest hundredth is, 69.08 cm

Explanation:

Circumference(C) of the circle is given by:

`C = 2\pi r` .....[1]

where,

r is the radius of the circle.

As per the statement:

middle of circle is 11 cm

⇒
`r = 11 cm`

use
`\pi = 3.14`

Substitute these in [1] we have;

`C = 2 \cdot 3.14 \cdot 11 = 69.08 cm`

Therefore, the circumference of the circle to the nearest hundredth is, 69.08 cm
