Answer:
-4
Step-by-step explanation:
53 = -19z+5+7z
53 = -12z+5 | -5 (on both sides)
48 = -12z | :(-12)
z = -4
C=2r
divide both sides by 2
c/2=r
c=2pir
divide by 2pi
c/(2pi)=r
The perpendicular line would be vertical and therefore undefined.
I saw the diagram.
1) radii: CD, CG, CF, CE, CH
2) diameter: DG, EF
3) radius: 14cm/2 = 7cm
4) diameter: 14cm because DG is the diameter, its measure is the measure of the diameter.
5) Circumference = 2 π r = 2 * 3.14 * 7cm = 43.96cm
6) Area = π r² = 3.14 * (7cm)² = 3.14 * 49cm² = 153.86 cm²
Answer:
5 because you have to count the numbers in between.
