Answer:
Step-by-step explanation:
A = C^2 / 4 x pi
so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).
you would then just divide 100 by 12.57 = 7.96 ( rounded)
hope it helped
Answer:
The mean is 85.25
The medium is 86
The mode is 92
Step-by-step explanation:
The mean is all the numbers added divided by the number of values.
77 + 92 + 80 + 92 divided by 4
341 divided by 4 = 85.25
The median is the middle number
92 + 80 divided by 2
172 divided by 2 = 86
The mode is the number that occurs the most which is 92.

Answer:
All four Sets didn't work
Step-by-step explanation:
You should be doing hypothnose aka: a² + b² = c²
If they both equal that means they are a right triangle.
Set 1:
24² + 26² = 110²
576 + 676 = 10²
1252 = 12100
No
Set 2:
2² + 4² = 6²
4 + 16 = 6²
20 = 36
No
Set 3:
13² + 14² = 15²
169 + 196 = 15²
365 = 225
No
Set 4:
10² + 20² = 30²
100 + 400 = 30²
500 = 900
No
