Are the two cylinders similar? The diagrams are not drawn to scale. (2.8, 12.5)

ya

Step-by-step explanation:

they are both cylinders

im not smart

Just took this test and got it right, it's impossible to tell, unfortunately. We know one value of one cylinder, and the other value we need in the other cylinder. We're given the radius of one, not both, and the same goes for the height. Therefore, we can't possibly find out if the two are similar with the information given. Hope this helps!

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
