9 x 9 x 21 = 1,701 hope this helps
<span>You are given the number 120 that is separated into 2 parts. You are also given that the larger part exceeds three times the smaller by 12. You are asked to find the the size of the smaller part. To solve this, establish an equation. Let us denote x as the size of the smaller part.
It is also said that "l</span>arger part exceeds three times the smaller by 12" and converting it into an equation, we have
<span>3x + 12
And since the sum of two parts is 120, equate 3x + 12 to 120
3x + 12 = 120
3x = 120 - 12
3x = 108
x = 36

Given:
Cylinder = radius 2cm ; height 4cm
graduated cylinder = radius 3cm w/ liquid
Volume of a cylinder = π r² h = 3.14 * (2cm)² * 4cm = 50.24 cm³
Volume of a cylinder = Volume of the graduated cylinder
50.24 cm³ = 3.14 * (3cm)² * h
50.24 cm³ = 28.26 cm² * h
50.24 cm³ / 28.26 cm² = h
1.78 cm = h
<span>The liquid rises by 1.78 cm in the graduated cylinder.</span>
