Answer:
9
Step-by-step explanation:
area of a circle = pi times radius^2
254.34= 3.14 X r^2 get rid of 3.14 by dividing both sides by 3.14
254.34/3.14= r^2
81= r^2
find the square root of 81=9
125/380 i think is the answer
Answer:
The fraction of the students play soccer = 
Step-by-step explanation:
Given - In the town of Destin, 2/3 of the students in middle school participate in organized sports after school.
To find - If 3/5 of them play soccer, what fraction of the students play soccer? Enter your answer in simplest form
Solution -
Let us assume that,
Total number of students in the middle school = 3x
Now,
Given that
2/3 of the students in middle school participate in organized sports after school.
So,
Total students participated in organized sports = (2/3)×3x
= 2x
⇒Total students participated in organized sports = 2x
Now,
Given that,
3/5 of them play soccer
So,
Total players who play soccer = (3/5)×2x
= 6x/5
⇒Total players who play soccer = 6x/5
Now,
The fraction of total students play soccer = (6x/5) ÷ (3x)
= 
= 
∴ we get
The fraction of the students play soccer = 
a. 28 * 63
28 (60) + 28 (3) or 20 (60) +20 (3) + 8 (60) + 8 (3)
1680 + 84=1764 1200 / 60 +480 +24=1764
b. 17(59)
17 (50) + 17 (9) or 10 (50) + 10 (9) + 7 (50) +7 (3)
850 + 153=1003 500 + 90 + 63 =1003
c.458 (15)
458 (10) +458 (5) or 10 (400) + 10 (50) + 10 (8) + 5 (400) +5 (50) + 5 (8)
4580 +2290 = 6870 400 + 500 + 80 + 2000 + 250 + 40 = 6870
My work is kinda confusing but hope it helped
