Answer:
choice 3) 11,488.21 cm³
Step-by-step explanation:
r= 28/2 = 14
volume = 4/3πr3 = 4/3(3.14)(14³) = 11,488.21 cm³
Hey there! :D
Let's find what Cheyenne runs in 10 minutes.
Divide 5.6 by 4.
5.6/4= 1.4
Multiply that by 6. (there are 60 minutes in an hour)
1.4*6= 8.4
"B" is the answer.
I hope this helps!

Answer:
28 m
Step-by-step explanation:
The top angle in the triangle = 90° - 62° = 28°
Using the cosine ratio in the right triangle
cos28° = 
= 
cross- multiply
x × cos28° = 25 ( divide both sides by cos28° )
x = 
= 28.31425... ≈ 28 m
Thus the distance from the top to the crocodile is 28 m
Answer: 5 benches and 23 students
Step-by-step explanation:
I will answer in English.
We have E students and B benches.
If we sit 4 students per bench, we have 3 students left.
then:
E = 4*B + 3
And if we sit 5 students per bench, there are two places with no students sited.
E = 5*B - 2
now we can replace the E in the second equation with the right part in the first equation:
4*B + 3 = 5*B - 2
3 + 2 = 5*B - 4*B
5 = B
So we have 5 benches, and:
E = 4*5 + 3 = 23 students.
