How does the volume of an oblique cylinder change if the radius is reduced to 2/9 of its original size and the height is quadrup

vesna_86 [32]

Volume of a cylinder = π r² h

Let us assume the following values:
radius = 9
height = 10

Volume = 3.14 * 9² * 10
= 3.14 * 81 *10
Volume = 2,543.40

Changes:
radius is reduced to 2/9 of its original size = 9 x 2/9 = 2
height is quadrupled = 10 x 4 = 40

Volume = π r² h
= 3.14 * 2² * 40
= 3.14 * 4 * 40
Volume = 502.40

Original volume = 2543.40 V.S. Volume after change = 502.40

The volume of an oblique cylinder decreased when its radius was decreased to 2/9 of its original size and its height is increased 4 times.

Meredith solved a quadratic equation. Her work is shown below.

Damm [24]

Answer:

Step 2

Step-by-step explanation:

Meredith made a fatal mistake or error in step 2;

Any quadratic problem will always have two solutions. Therefore since, we only have one solution here, it is wrong. The mistake was incurred in step 2;

From the given problem ;

<u> Wrong right</u>

2(x + 4)² = 242

(x + 4)² = 121 Step 1

x+4=11 Step 2 x + 4 = ± 11

x = 7 Step 3 x + 4 = 11 or x + 4 = -11

x = 11- 4 or x = -11 - 4

x = 7 or -15

When can you say that there is no solution for a system of linear equation

SCORPION-xisa [38]

Answer:

You can say there is no solution for a system of linear equation when the graphs are PARALLEL to each other.

ONE solution: when both lines intersect at one point

INFINITE solution: when the line goes on forever

NO solution: is when the lines are parallel to each other.
