Step-by-step explanation:
By quadrant I presume you mean 1/4 of the circle. The perimeter will be 1/4 of the circle’s circumference plus the length of the two radii that complete the 1/4 section.
C=2 × pi × r = 28 pi
Perimeter = 28 pi +14+14. using 22/7 for pi
22/7 × 28 +28 = 88 + 28 = 116
116 cm is perimeter
Hope my answer will be correct

hope you don't mind but im using this for points
Answer: n=1.8
Step-by-step explanation:
6n+14=25
-14 on both sides
25-14=11
6n=11
divide 6 on both sides
n=1.83333..
The picture is a bit blurry but what I saw was 8a^3+27=0
8a^3+27=0 first you move 27 to the right side of the equation
8a^3=-27 then you divide both sides by 8
a^3 = -27/8 then take the cubed root of both sides
a= -3/2
Hope that helps ;)
