General Formulas and Concepts:

Geometry

Area of a Circle Formula: A = πr²

  • r is the radius

Step-by-step explanation:

Step 1: Define

Identify given.

r = 3

Step 2: Find Area

  1. [Area of a Circle Formula] Substitute in radius r:
    A = π(3)²
  2. Evaluate:
    A = 9π
  3. Approximate:
    A ≈ 28.2743

∴ we have found our exact area to be 9π and our approximate area to be 28.2743.

Answer:

heya! ^^

we've been given that the radius of the circle is 3.

and we've to find the area of the circle to its closest approximation.

Firstly ,

[tex]Area \: of \: circle = \pi \: r {}^{2} \\ \\\dashrightarrow \: \frac{22}{7} \times 3 {}^{2} \\ \\\dashrightarrow \: \frac{22}{7} \times 9 \\ \\\dashrightarrow \: 28.285714 [/tex]

closest approximation = [tex] 28.29 \: units^{2} [/tex]

hope helpful :D
