Question

What is the area of this figure use 3.14 for pi

Answer 1

Answer:

Area of the figure is 22.28ft²

Step-by-step explanation:

The figure is made up of a semicircle and a square.

The area of the figure = area of semicircle + area of square

Area of square L² where

L is length of the square = 4² = 16ft²

Area of a semicircle = πr²/2

The radius of the semicircle = 4/2 = 2ft

Area of semicircle = π(2)²/2

Area of semicircle = 4π/2

Area of the semicircle = 2πft² = 6.28ft²

Area of the figure = 16ft + 6.28ft²

Area of the figure = 22.28ft²

Answer 2

Area of a square is a².

4² = 16

Now find the area of the semicircle.

(πr²)/2
(3.14)(2)²/2
12.56/2
6.28

Now add the areas to find the total area.

6.28 + 16 = 22.28

Hope this helps :)
