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.

dimulka [17.4K]

Answer:

The measure of angle x is 50 degrees

Step-by-step explanation:

we know that

$x+y=90$ ----> equation A

$x=2y-30$ ----> equation B

solve the system by substitution

substitute equation B in equation A

$(2y-30)+y=90$

solve for y

$3y=90+30$

$3y=120$

$y=40^o$

Find the measure of angle x

$x=2(40)-30=50^o$

therefore

The measure of angle x is 50 degrees

(1).probability of getting a red marble is.

total number of red marble is 2.

total number of marble is 10.

$p(e) = \frac{2}{10} = \frac{1}{5}$

(2). probability of getting a blue marble is

total number of blue marble is 3.

total number of marble in bag is 9

$p(e) = \frac{3}{9} = \frac{1}{3}$
