Answer:
circumference is 18.84
area is 28.26
Step-by-step explanation:
circumference of a circle is
2πr where r is radius
= 6×3.14= 18.8
area of a circle is πr²
= 3×3×3.14
= 28.26
use π = 3.14

Answer:
No
Step-by-step explanation:
If the lines are perpendicular then they will be the negative reciprocals of each other.
Calculate the slope using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)
=
= - 
Repeat the process with
(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)
=
= 
The slopes are not the negative reciprocal of each other, thus they are not perpendicular.
