Answer:
<h3>The radius is 7 cm</h3>
Step-by-step explanation:
Volume of a sphere is given by
where r is the radius
From the question V = 1436 cm³
Multiply through by 3
We have
Divide both sides by 4π
Find the cube root of both sides
![r = \sqrt[3]{ \frac{1077}{\pi} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B1077%7D%7B%5Cpi%7D%20%7D%20)
r = 6.99
We have the final answer as
<h3>r = 7cm</h3>

Answer:
There were 4 adults; including Mr. Torres
Step-by-step explanation:
- Each row in the stadium had 9 seats
- Mr. Torres sat by himself; he sat on a row with nobody else (no students, no adults)
- The arrangement of the students and the adults who sat with them on same row is: A S S S A S S S A
1 2 3 4 5 6 7 8 9
since 1 adult sat at each end of a/the row and each group of 3 students was seated between 2 adults.
So the total number of adults that were present = 3 + 1 = 4
