Answer:
Step-by-step explanation:
V=4/3πr^3
V=1.333×3.14×27ft
V=113.04ft
Idk I'm learning that also
Answer:
Step-by-step explanation:
1)
Tri. prism:
B = base = 1/2 a c
base = 1/2 * 6 * 6 = 18
volume = Bh
v = 18*4
v = 72
Rec. prism
volume = 4*6*6
v = 144
total volume = 144+72
vt = 212
2)
top rec. = 2*3*5=30
bot rec. = 4*5*6=120
vt = 30 + 120
vt = 150
Answer:
not similar
Step-by-step explanation:
32/26 = 16/13
18/12 = 3/2
16/13 is not equal to 3/2, so the rectangles are not similar.
