Olá, minha primeira vez aqui, queria muito poder entender estes exercícios mas não consigo, já fiquei 2 dias nisso e não entendo mesmo, não consigo resolver O volume do cilíndro é V=pi. r^2.h que tem como resultado 10048cm^3, não sei como fazer o resto, as aulas do professor são gravadas então não consigo perguntá-lo

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
