Area of a circle mathswatch answrts

Mathematics
1 answer:
hichkok12 [17]3 years ago
4 0

Answer:

The area of a circle can be calculated by using the formula:

A = πr²

Step-by-step explanation:

I'm assuming that you are asking about how to calculate the area of a circle, so this formula would be it, where the symbol 'π' is pi, a number which never ends, but in calculations is typically rounded to 3.14. However, on your calculator you may have a button which you can press to find the area of a circle that way.

Area of the figure = 30.28 m²

Solution:

The given image is splitted into two shapes.

One is rectangle and the other is semi-circle.

Length of the rectangle = 6 m

Width of the rectangle = 4 m

Area of the rectangle = length × width

                                    = 6 m × 4 m

                                    = 24 m²

Area of the rectangle = 24 m²

Diameter of the semi-circle = 4 m

Radius of the semi-circle = 4 m ÷ 2 = 2 m

Area of the semi-circle = \frac{1}{2} \ \pi r^2

                                      $=\frac{1}{2} \times 3 .14 \times 2^2

                                      =6.28

Area of the semi-circle = 6.28 m²

Area of the figure = Area of the rectangle + Area of the semi-circle

                              = 24 m² + 6.28 m²

                              = 30.28 m²

Area of the figure = 30.28 m²
