Answer:
8cm
Step-by-step explanation:
Since the area of a square is Side X Side (s x s) it is also s². The s² is also equivalent = 64cm². To find the length of a side you do the √64cm² and you get 8cm for a side. Great Job!
Circumference is found by evaluating C = 2 pi r, where r is the radius of the circle. Here, C = 2 pi (2.4 cm) = 4.8 pi.
When you round to the nearest hundredth, you round to two numbers after the decimal place
So the answer is 80.16
The 5 becomes a 6 because the number after it (9) is larger than 5
Hope this helps
