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.
Let
. You have derivatives
and
. Then
From the last equation, you have
. Plug this into the second equation to get
. Plug these into the first to get
.
So the polynomial is
The answer is (12DS)/cd=w
Answer:
h = 19 mm
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the base and h the height )
the base is a regular pentagon whose area (A) is calculated as
A = pa ( p is the perimeter and a the apothem )
p = 5 × 12 = 60 mm and a = 5 mm , then
A = × 60 × 5 = 30 × 5 = 150 mm²
given V = 2850 , then
150h = 2850 ( divide both sides by 150 )
h = 19 mm
