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.
Sometines like with 4 and eight thats 4 but with others like 2 and 4 its 2
hope it helps
Answer:
Length = 32 feet
Width = 12 feet
Step-by-step explanation:
From the question;
Width = w
Length = 2w + 8
But the perimeter of a rectangle = 2(l + b)
perimeter = 88 feet
88 = 2(2w + 8 + w)
88 = 2(3w + 8)
88 = 6w + 16
88 - 16 = 6w
72 = 6w
w = 72/6
w = 12 feet
Hence;
Length = 2(12) + 8 = 32 feet
Dimensions of the rectangle is;
Length = 32 feet
Width = 12 feet
Answer:
Step-by-step explanation:
to solve an equation by completing the square in a quadratic formula
f(x)=ax²+bx+c
example :x²-6x-16=0
first rearrange if necessary, move the constant to one side .
x²-6x=16
second you find a new term to complete the square which is (b/2)², and add the term to both sides.(6/2)²=3²=9
x²-6x+9=16+9
x²-6x+9=25
third factorize : find the common factor between 6 and 9 which is 3
x²-6x+9=25
(x-3)²=25
last solve for x: (x-3)²=25
x-3=√25
x=3±5
x=3+5=8 or 3-5=-2
