Question
The Large Hadron Collider at a research lab is contained in a circular tunnel with a circumference of 26.7 km. What is the radius in kilometers of the circular tunnel in terms of π?
Enter the correct answer in the box.
[ ]km
Answer:
13.35/π km or 26.7/2π km
Step-by-step explanation:
“In terms of π” means leave pi in the answer. No need to use a decimal equivalent.
The radius is half of the circumference divided by π.
Answer:
4.2494369805536 km
Step-by-step explanation:
r = 4.2494369805536km because 26.7/2π which means:
26.7 ÷ 3.14159265359 x 2 = 4.2494369805536 km.
