<h2><u>Question</u>:-</h2>
Find the volume of a cylinder with a radius of 3 meters and a height of 13 meters.
<h2><u>Answer</u>:-</h2>
<h3>Given:-</h3>
Radius (r) of a cylinder = 3 meters.
Height (h) of a cylinder = 13 meters.
<h3>To Find:-</h3>
The volume of a cylinder.
<h2>Solution:-</h2>
We know,
Formula of Volume of a cylinder is πr²h.
So, Volume of a cylinder = 3.14 × (3)² × 13
Volume of a cylinder = 3.14 × 3 × 3 × 13
Volume of a cylinder = 367.38 cubic meters.
<h3>The volume of a cylinder is <u>3</u><u>6</u><u>7</u><u>.</u><u>3</u><u>8</u><u> </u><u>cubic </u><u>meters</u>. [Answer]</h3>

(f×g)(-1) is -14.
Step-by-step explanation:
- Step 1: Calculate (f×g)(x) by using the formula (f×g)(x) = f(x) × g(x)
⇒ (f×g)(x) = (x + 3)(4x - 3)
⇒ (f×g)(x) = 4x² - 3x + 12x - 9
⇒ (f×g)(x) = 4x² + 9x - 9
- Step 2: Find (f×g)(-1) by substituting -1 in the place of x
⇒ (f×g)(-1) = 4(-1)² + 9(-1) - 9
⇒ (f×g)(-1) = 4 - 9 - 9 =-14

It can be expressed as a fraction with integer numerator and denominator, so it's a rational number.
