Answer:
Step-by-step explanation:
circumference of cylinder = πd = 5π in
lateral area of cylinder = 5π×9 = 45π in²
Each colored face has a matching face on the other side of the figure.
green areas = 2(17×15) = 510 in²
blue areas = 2(12×17) = 408 in²
gray areas = 2(5×6) = 60 in²
yellow areas = 2(5×12) = 120 in²
red areas = 2(12×15) = 360 in²
total surface area = 45π + 510 + 408 + 60 + 120 + 360 ≅ 1,599.37 in²
Answer:
It will take 58 seconds
Step-by-step explanation:
If you have 1 kg of water in the jar, half of it will be 0.5 kg.
To vaporize half of the water (0.500 kg) the energy supply needed is
If the stove is supplying 20 kJ/s, the time its needed is
It will last at least 58 seconds to vaporize half of the water.
