Answer:

282.7

Step-by-step explanation:

surface area of cylinder = 2πR² + 2πRh

R = 3 cm

h = 12 cm

surface area of cylinder = 2π*3² + 2π*3*12 = 90π ≈ 90*3.14 ≈ 282.7 (cm²)

Y=4x−9<br> Complete the missing value in the solution to the equation

weeeeeb [17]

Answer:

<h2>The missing value is 3, and the coordinates are (3,3).</h2>

Step-by-step explanation:

The complete question is

$y=4x-9$

Complete the missing value in the solution to the equation. (3, ? )

By given, we know that $x=3$ , because coordinates are written like $(x,y)$ .

Then, we replace the given coordinate to find $y$ .

$y=4x-9\\y=4(3)-9\\y=12-9\\y=3$

Therefore, the missing value is 3, and the coordinates are (3,3).
