R1² π : r2² π = 9 : 1.44
r1 : r 2 = 3 : 1.2
r2 = 1.2 · r1 / 3
r 2 = 0.4 · r1
If the two cylinders are similar than also: h 2 = 0.4 · h 2
V 1 = r1² · π · h1
V 2 = ( 0.4 r1)² π · 0.4 · h1 = 0.064 r1² · π · h1
V 2 ( small cylinder )= 0.064 · V 1 ( large cylinder )
851.22 m³= 13.300.25 m³ · 0.064
Answer: C )
Answer: candle burns down 1 cm per hour
Step-by-step explanation:
<span>An exterior angle of a triangle is equal to the sum of the opposite interior
angles </span>⇒ x = 30 + 90 = 120°
I'm assuming it would be the same shape? That's also assuming that it's referring to congruent shapes and angles.
Answer is D.
Just plug in 2 for x and -2 for y. And solve
