Question

Find the area of this circle. Use 3 for .
A = r2
12 cm
[?] cm2

Answer 1

Explanation:

`area = \pi {r}^(2) \\ = \pi * {12}^(2) \\ = \pi * 144 \\ = 3.14 * 144 \\ = 452.16 {cm}^(2) \\ thank \: you`

Answer 2

452.16 cm²

Explanation:

Given :-

• Radius = 12cm .

To find :-

• Area of circle .

Solution :-

As we know that ,

• A = πr²
• A = 3.14 * (12 cm)²
• A = 3.14 * 144cm²
• A = 452.16 cm²
