Answer:
D. 4(s + 3) & (s + 3) + (s + 3) + (s + 3) + (s + 3)
Step-by-step explanation:
We know this is a square (which is a polygon, which requires at least 3 sides), so A & B are out. C is also out because of the first expression. All 4 sides are s + 3; what the first expression on C is saying is we're adding a 5th side of 3 to 4 sides with length s. That leaves D as our answer. Bonus: Another expression that could work for this is 4s + 12 (which is both of D's expressions simplified.).
Answer: Length of arc = 12.6 cm
Step-by-step explanation:
CD is an arc. We would apply the formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Diameter = 24 cm
Radius, r = diameter/2 = 24/2
Radius = 12 cm
θ = 60 degrees
Therefore,
Length of arc = 60/360 × 2 × 3.14 × 12
Length of arc = 12.6 cm rounded up to the nearest tenth.
