Answer:
Step-by-step explanation:
cylinder's height=3×(diameter of sphere)=3×6=18 cm
radius of cylinder=3 cm
volume of cylinder=π r²h=π(3)²×18=162 π cm³
volume of sphere=4/3 π(3)³=36 π cm³
reqd. empty space=162 π-3×36π=54 πcm³
The first one in incorrect , it should be 130 but the rest are correct !
I think it would be 4.7A - C
No regrouping: 4.34 + 4.35
Regrouping (carrying): 4.93 + 3.76
