The circumference is 81.68 mm. C= 2pi(r)
345 in Standard Form is 3.45 x 10^2

Answer:
mean: 8.9, median: 9, mode: 3, range: 14, standard deviation: 5.1
Step-by-step explanation:
The mean is all the numbers added up, divided by how many numbers there are. To get the median you arrange the numbers biggest to smallest and find the middle number.
I’m pretty sure the answer would be A because the 5 makes the 9 round up to ten and then the 7 becomes an 8.
