I HOPE YOU CAN ALSO GIVE THE PRECISE ANSWER!BEST OF LUCK!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Way less ribbon than you might think.

the answer is C and the precise answer is 0.00628 km(pi=3.14)

6.28318 km is my answer, so the answer is c

Explanation: You take 40070 and divide it by pi(i used 3.14159) and get 12754.687912

and you add 2

so you get 12756.687912

and you multiply it by pi

and you get 40076.28318

subtract 40070

you get 6.28318

First of all, you should be adding 2 m, not 2 km. Secondly, the answer is independent of the radius of the earth, making it the same for all circular object in the universe. Neat huh?

Adam Silvernail - 8 years, 2 months ago
