Answer:
58.6 cm;
20.1 m
Step-by-step explanation:
✔️Length of arc = θ/360 × 2πr
Where,
θ = 240°
r = 14 cm
π = 3.14
Plug in the values:
Length of arc = 240/360 × 2 × 3.14 × 14
= 58.6133334 = 58.6 cm (nearest tenth)
✔️Length of arc = θ/360 × 2πr
Where,
θ = 105°
r = 11 m
π = 3.14
Plug in the values:
Length of arc = 105/360 × 2 × 3.14 × 11
= 20.1483334 = 20.1 m (nearest tenth)
Answer with Step-by-step explanation:
We are given that
ABCE is a rectangle .Rectangle is that quadrilateral in which opposite sides are equal and each is equal to 90 degrees.
D is the midpoint of E.
We have to prove that 
Statement:1 ABCE is a rectangle.D is the mid point of CE
Reason: Given
Statement 2:
Reason:By definition of rectangle
Statement:3 AE=BC
Reason: By definition of rectangle
Statement 4:
Reason: By definition of midpoint because D is the midpoint of side EC
Statement 5:
Reason:SAS postulate
Statement: 6 
Reason:CPCT
Hence proved.
First you find your slope which is rise/run, so, 1/3, and a line this way (/) is positive, so it's positive 1/3.
Then you see where it crosses the y axis: -1.
Plug that into y=mx+b giving you y=1/3x-1.
Your answer is D.
Answer- 7.65 cm
explanation- the perimeter is just all the the sides lengths added together. since we know a square has four equal sides, we know that each side has to be the same length. so you divide 30.6 by 4 to get 7.65 cm.
15 is the awnser too this one
