Question

I may be a bit smart but It's the morning and I'm tired so here's one: A crop circle has a radius of 25.7 meters. Which value below would be the circumference of the circle? Use 3.14 for π and round your answer to the nearest tenth.

Answer 1

161.40 meters

Explanation:

Circumference of a circle = 2×π×r

π = 3.14

Radius, r = 25.7 meters

Circumference of a circle = 2×π×r

= 2 × 3.14 × 25.7

= 161.396

To the nearest tenth = 161.40 meters
