Question

Gavin is measuring the distance around some pine trees in the local state park. He is trying to find the biggest pine tree in the forest. He finds several trees with circumferences greater than 1.8 meters. What is the minimum diameter of one of those trees?

Answer 1

0.58 meters

Explanation:

If he find several trees with circumferences greater than 1.8 meters.

C>1.8

Circumference of a circle =
`\pi d`

Therefore:

`\pi d>1.8\\d>1.8 / \pi\\d>0.57`

Therefore
`d\geq 0.58`

Therefore, the minimum diameter of one of the trees is 0.58 meters correct to 2 decimal places.
