Volume of a cone = 1/3 r² π h
Volume of a cylinder = r² π h = 3 · V ( cone ) = 3 · 12 = 36 in³
Answer: C )
Answer:
perimeter of the rectangle is 64
so
64=2(3y+2+2y)
32=5y+2
30=5y
6=y
so
PQ=3×30+2=92
Answer:
2175
Step-by-step explanation:
y = k sqrt(x)
x = 625
y = 87
87 = k * sqrt(625)
87 = k * 25
87/25 = k
k = 3.48
y = 3.48 * sqrt(390625)
y = 3.48 * 625
y = 2175
