Answer:
24.997 cm
Step-by-step explanation:
Find the diameter:
7(2) = 14 cm
Find the circumference:
C =
C =
C = 43.988
Divide the circumference by 4:
43.988/4 = 10.997
(This is the length of the curved side)
Add length to the other 2 sides:
7 + 7 + 10.997 = 24.997
Answer:
Option A: is the correct answer.
Step-by-step explanation:
Given that:
Slope of the line =
Let,
m be the slope of the line perpendicular to the line with slope
We know that,
The product of slopes of two perpendicular lines is equals to -1.
Therefore,
Multiplying both sides by
m =
is the slope of the line perpendicular to the line having slope
Hence,
Option A: is the correct answer.
