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)
Step-by-step explanation:
1. set it equal to 0 so t=5,9
2. this is wriiten in vertex notation so vertex is (7,4)
Ultimately, it is impossible to solve an equation without two sides. If it was 2X=2, the answer would be X=1. But if it was 2X+2=0, the answer would be X=-1. The information given is impossible to work with,
The first questions answer is 50.
The second questions answer is 480
The third is 90
The fourth answer is 180
Lastly the last answer is 180 again
The answer to your question is $11.50
