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 believe it would be the last answer, 6.25
if this is correct i’m very sorry, but if this helps, please mark brainliest. :)
Bro I’m rly sorry but I don’t know the answer to this
So, since the question is asking you what percentage 31.5% is of 473, you can multiply 31.5 by 473 and get <span>14899.5. But, you'll have to change this answer into a percentage. So, you can move the decimal point two places over, and end up with 148.995. Since the question says that you can round to the nearest whole number, you can go ahead and put down 149. Hope this helped.</span>
