Find the amount of empty space within a cylinder containing three solid spheres, where each sphere has a radius of 3 cm. (Volume
of a sphere =4/3πr^3)
1 answer:
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

Answer:
A
Step-by-step explanation:
The triangles are the same. Congruent is when all three sides are equal to each other on both triangles
2x+5y=20
X=10-2.5y
-2(10-2.5y)+20y=-90
-20+5y+20y=-90
25y=-70
Y=2.8
2(2.8)+5y=20
5.6+5y=20
5y=14.4
Y=2.88
CHECK:
2(2.8)+5(2.88)=20
