diameter (d) = 2 · r
Circumference (C) = 2 π · r → C = π · d → d =
42 is the number because...
42 ÷ 6 = 7
42 ÷ 7 = 6
Answer:
before midterm!
Step-by-step explanation:
I will try to research an answer in the meantime and i will add a comment to my answer when i find the answer to this
2) radius = 7
diameter = 14
A = 49π or 153.94
C = 14π = 43.98
3. radius = 9
diameter = 18
area = 81π or254.47
C = 18π = 56.55
