Answer:
3.14 square units
Step-by-step explanation:
Circumference of a circle = 2πr
2πr = 6.28
r = 6.28/2π
r = 3.142/π
Area of a circle = πr^2
slot in the value of r
Area of the circle = π( 3.142/π)^2
" = π(9.87/ π^2)
" = 9.87/π
π = 3.14
Area of a circle = 9.867/ (3.14)
" = 3.14 square units
I hope my explanation helps
Answer: I think it is SAS
Step-by-step explanation:
As a formula, you're saying 4*(n-7)=32
This solves to n-7 = 8, so n=15
Yes, the relationship is proportional. 3 * 3.2 = 9.6. And 5 * 3.2 = 16.
