Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
Answer:
180:270:720
Step-by-step explanation:
total units-> 13u
1 unit -> 1170÷13=90
2u->90×2=180
3u->90×3=270
8u->90×8=720
Answer:
an equation involving the unknown function y, its derivatives y' and y'', and the variable x.
Step-by-step explanation:
X/3-5=y
add 5 to both sides
x/3=y+5
now multiply both sides by 3
x=3(y+5)
which means
x=3y+15
