Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc =
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s =
Therefore, Option B will be the answer.
Answer:
Step-by-step explanation:
Move all terms containing b to the left, all other terms to the right. Add '81' to each side of the equation. -81 + 81 + b 2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + b 2 = 0 + 81 b 2 = 0 + 81 Combine like terms: 0 + 81 = 81 b 2 = 81 Simplifying b 2 = 81 Take the square root of each side: b = {-9, 9}
Answer:
72 in^3
Step-by-step explanation:
The volume is found by V=Bh meaning volume = area of the base * height
V = 6 * 12
V = 72
Y= 7- x/3
Im 100% sure, Im a math freak. These are the easiest for me.
The greatest common factor is 3.
