Which equation can be used to find the surface area of the cylinder

Phoenix [80]

2πr^2 + 2πrh.
r is the radius circle face.
h is the length/height of the cylinder.
πr^2 is the formula for circles, and there are 2 circles in a cylinder. So 2 x πr^2 would be determine the area of the 2 circles.
2πr is the formula for circumference. 2πr x h would the area of the curved face.

You have 5 Red Marbles, 4 Green Marbles, and 3 Blue Marbles in a Bowl. You randomly pick 4 marbles from the bowl (without replac

makvit [3.9K]

Answer:

Step-by-step explanation:

In this case each one is an independent event, therefore, the multiplication of each one would be the final probability

We have 5 Red Marbles, 4 Green Marbles, and 3 Blue Marbles, that is, there are 5 + 4 + 3 12 Marbles in total.

Now if I draw a red one, the probability would be: 5/12

When drawing another red, the probability would be: 4/11

When taking the green: 4/10

When removing the blue: 3/9

Finally, the final probability is:

P = (5/12) * (4/11) * (4/10) * (3/9)

P = 0.020

In other words, the probability of this happening is 2%

Lines a and b are parallel. When they are cut by transversals, they form a triangle Parallel lines a and b are cut by transversa

lord [1]

Answer:

Therefore, the angle 3 have 28 degrees.

Step-by-step explanation:

We know that the lines a and b are parallel. When they are cut by transversals, they form a triangle. Parallel lines a and b are cut by transversals s and t to form a triangle. Angle 1 is 90 degrees, angle 2 is 62 degrees.

We know that the number of degrees in a triangle equals 180.

We get:

$90+62+x=180\\\\152+x=180\\\\x=180-152\\\\x=28\\$

Therefore, the angle 3 have 28 degrees.
