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
Answer : Slope = 4 because y = mx+b
Y- intercept = 9
Any line can be graphed using two points values, and plug them into the equation to find the corresponding values.
