Question

Find the area of each figure and round to the nearest tenth if necessary.

Answer 1

-Area of square = 144 yd²

-Area of semi circle = 56.5 yd² (rounded to nearest 10th)

Explanation:

Area of square = 12 × 12

= 144 yd²

r of semi circle= 12÷2= 6yd

Area of semi circle

`= (1)/(2) \pi {r}^(2) \\ = (1)/(2) * \pi * {6}^(2) \\ = (1)/(2) * \pi * 36 \\ = 18\pi`

= 56.54866.....

= 56.5 yd²
