Step-by-step explanation:
Let the number Noah is thinking of be x,
=> x - 19 * 4 = 16
=> x - 19 = 16/4
=> x = 16/4 + 19
=> x = 4 + 19
=> x = 23

<h3>Option b is coreect</h3>
Answer:
<h2>
V ≈ 628.3 cm³</h2>
Step-by-step explanation:
Volume of cylinder: V = π×r² × h
diameter = 20 cm ⇒ r = 10 cm
h = 2 cm
Volume:
V = π×(10)²×2 = 200π cm³ = 628.318.... cm³ ≈ 628.3 cm³
Because AC is a diameter we can find the 180/3 = x
giving us the x= 60
Then that arc AB = 120
The triangle with the given coordinates X(6,1) Y(-2,-3) Z(0,3) is an isosceles triangle.
The given coordinates are X(6,1) Y(-2,-3) Z(0,3).
<h3>What are coordinates?</h3>
A coordinate system is a system in geometry that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold, such as Euclidean space, in a unique way.
We know that, Distance formula
