Volume of 1 ball = 4/3 π r³ = 4/3 (3.14) (2.25 ÷ 2)³ = 5.961 in³
Volume of 3 balls = 5.961 x 3 = 17.883 in³
Volume of cylinder = πr²h = (3.14) (2.25 ÷ 2)² (6.75) = 26.825 in³
Empty Space = 26.825 - 17.883 = 8.94 in³ (nearest hundredth)
Answer: 8.94 in³
Answer:
54
Step-by-step explanation:
Answer:
m<B = 141 degrees
Step-by-step explanation:
This shape is a heptagon meaning its angles should have a sum of 900 degrees.
we are given the degrees and we need to ad them up
148+90+120+129+130+142=749
then we subtract 749 from 900 which looks like
900-749=141
from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees
Answer is 125.
Because it's cube root is an integer:)
