Answer:
Either B or C but i'll have to say B if I had to choose.
Step-by-step explanation:
As we can tell it decreases slowly.
The radius of the circle with arc length 40cm and central angle is 60 degree is 38.24 cm.
According to the given question.
Arc length of the circle = 40cm
Central angle, θ = 60 degrees
As, we know that the arc length of the circle, s with the radius r and central angle θ by using the formula
s = θ × (π/180)r
Therefore, the radius r of the circle with arc length 40cm and central angle 60 degrees is given by
40 = 60 × (3.14/180) r
⇒ 40/60 = 0.01744r
⇒ 0.66 = 0.01744r
⇒ r = 0.66/0.01744
⇒ r = 38.240
⇒ r = 38.24 cm
Hence, the radius of the circle with arc length 40cm and central angle is 60 degree is 38.24 cm.

Answer:
Area is the total surface covered by the shape and perimeter is the total length of the shape.
Answer:
Step-by-step explanation:
1/2 (2x+8)=3x+8−x
Use the distributive property to multiply 1/2=0.5 by 2x+8.
1/2 x 2x+1/2x8=3x+8-x
Cancel out 2 and 2.
x+1/2 ×8=3x+8−x
Multiply 1/2 =0.5 and 8 to get 8/2=4.
x+8/2=3x+8−x
Divide 8 by 2 to get 4.
x+4=3x+8−x
Combine 3x and −x to get 2x.
x+4=2x+8
Subtract 2x from both sides.
x+4−2x=8
Combine x and −2x to get −x.
−x+4=8
Subtract 4 from both side
−x=4
Multiply both sides by −1.
x=−4
