Question

Estimate the radius of the object

Answer 1

r = 1.41 mm

Explanation:

Given that,

The circumference of the flower, C = 8.9 mm

We need to find its radius. We know that,

Circumference,
`C=2\pi r`

Where

r is the radius of the object

`r=(C)/(2\pi)\\\\r=(8.9)/(2\pi)\\\\r=1.41\ mm`

So, the radius of the object is equal to 1.41 mm.
