A cup was filled at a constant rate. it started empty. after 2 seconds, it held 70 cm cubes of water. the radius is 4 and te height is 7. find the percent of the cup that is filled with water after 3 seconds. this is a cone

89.51%

Step-by-step explanation:

Assuming given units are in cm

Tge rate of filling the cup is 70/2= 35 cm3/s

Volume of the cup is and replacing r with 4 cm and h with 7 cm then the volume is equivalent to

Volume filled after 3 seconds will be 3*35=105 cm3

Percentage filled is

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
