1 answer:
Answer:
≈ 20 m
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ) , then
C = 2π × 3.2 = 6.4π ≈ 20
length of fence needed is approximately 20 m

67 with the remainder of 31 I hope this helps lol
Answer:
this question doesnt make sense as its like half of it
1. Observe question
2. Employ Point-Slope formula
(y2 - y1)/(x2 - x1 )=
(-10-9)/(-6-9) =
-19/-15=
19/15
Slope: 19/15
It's 4 units right and 3 units up :)
