Answer:

176.625 sq.ft, 4.8 sq.ft

Step-by-step explanation:

Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.

I can answer 1 to 4...
The area of a circle can be found by $\pi r^{2}$ . Reminder: $\pi = 3.14$ (usually used when finding out the area of a circle)

1. $4^{2} = 16$
$\pi *16$ or $3.14 * 16 = 50.24$
$50.24/4=12.56$

2. $6^{2} = 36$
$\pi *36$ or $3.14 * 36 = 113.04$
$113.04/10=11.304$

(Not really sure if this is correct) 3. $2^{2}=4$
$\pi *4$ or $3.14 * 4$
$12.56/2.66666667=11.70999999$

4. $6^{2}=36$
$\pi *36= 113.04$
$113.04/6=18.84$
