Answer:
113.1 unit²
Step-by-step explanation:
A cylinder is a shape with two round ends and two parallel lines connecting the round ends.
Height=9 unit, Base=4 unit
The lateral surface area of a cylinder (A) is given by the equation:

where r is the radius of the cylinder and h is the height of the cylinder.
Given that the base = 4 unit, therefore the diameter (d) = base = 4 unit. Also the height (h) = 9 unit.
Radius (r) = d/2 = 4/2 = 2 unit
Calculating the area of the cylinder is as follows
The area of the cylinder is 113.1 unit²
Answer:
1/14
Step-by-step explanation:
Assuming you mean that there are 2 red, 2 green, and 4 blue marbles, there are a total of 8 marbles.
On the first draw, the probability the marble is red is 2/8.
On the second draw, there's one less marble, so the probability of selecting a green marble is 2/7.
The total probability is:
2/8 × 2/7 = 1/14
What? is this a question? or....is it not?
Use your calculator put all of them together then you’ll get your answer
It’s a 60 degree angle :)
