Your answer would be the last option, D.
This is because spinning the spinner does not affect which marble you pick, as these are mutually exclusive events. This means that if the spinner lands on red, you could choose a black or white marble, and if the spinner lands on green you could also choose a black or white marble.
The only sample space that represents this is D because it's the only one that includes both black and white options after spinning red and green.
I hope this helps!
The amount of metal used to make the can = surface area of cylindrical can, which is: D. 42π in².
<h3>What is the Surface Area of a Cylinder?</h3>
A can is a cylinder.
Surface area of a cylinder = 2πrh + 2πr²
Thus:
Amount of metal used to make the can = surface area of the can
r = 6/2 = 3 in.
h = 4 in.
Therefore:
Surface area = 2×π×3×4 + 2×π×3²
Surface area = 24π + 18π
Surface area = 42π in².

Answer:
186 cm
Step-by-step explanation:
Since the bicycle wheel is making a rotation and not a revolution, the bicycle wheel is at one point.
The length of the trace of water left on the floor is simply the circumference of the bicycle wheel
Circumference = 2πR
where R = radius of the bicycle wheel
and π = pie
Circumference = 2 × (22/7) × 30 = 188.57143 cm
