Afaucet is filling a hemispherical basin of diameter 60 cm with water at a rate of 2 lymin. find the rate at which the water is rising in the basin when it is half full. [use the following facts: 1 l is 1000 cm3 . the volume of the portion of a sphere with radius r from the bottom to a height h is v − (rh2 2 1 3 h3 ), as we will show in chapter 5.]

sorry i dont know my friend

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
