Answer:
1 : 8
Step-by-step explanation:
For similar figures with ratio of sides = a : b
Then ratio of areas = a² : b² and
ratio of volumes = a³ : b³
Given ratio of areas = 1 : 4
linear ratio =
:
= 1 : 2
ratio of volumes = 1³ : 2³ = 1 : 8
7/5h+3/5h-2=7
10/5h-2=7
2h=11
h=5.5
7.87 is what i got :) good luck!!
The answer is the first one:
bc its not growing by a (-)1/2 and the 3rd one just doesnt make sense
Answer:
√(V / π × h), where V is the volume of the cylinder, h is the height, and π(Pi) is a mathematical constant with an approximate value of 3.14
