A. 80 students
B. 12 students
Step-by-step explanation:
![\pi {r}^{2} \frac{h}{3}](https://tex.z-dn.net/?f=%5Cpi%20%7Br%7D%5E%7B2%7D%20%20%5Cfrac%7Bh%7D%7B3%7D%20)
π×4×4×8/3
π×16×8/3
128/3×π
128/3π cm²
The ratio is 91/120 because 91 is only divisible by 1, 7, 13, 91 and 120 is not divisible by 7, 13, or 91 so you cannot reduce this ratio
Both Coordinates should be negative
Answer:
![2 sin^2 \theta](https://tex.z-dn.net/?f=2%20sin%5E2%20%5Ctheta)
Step-by-step explanation:
According to the scenario, the following information is given:
![= \frac{sec^2 \theta - 1 }{sec^2 \theta}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Bsec%5E2%20%5Ctheta%20-%201%20%7D%7Bsec%5E2%20%5Ctheta%7D)
![= (\frac{1}{\frac{cos^2\theta}{\frac{1}{cos^2\theta} }} - 1)](https://tex.z-dn.net/?f=%3D%20%28%5Cfrac%7B1%7D%7B%5Cfrac%7Bcos%5E2%5Ctheta%7D%7B%5Cfrac%7B1%7D%7Bcos%5E2%5Ctheta%7D%20%7D%7D%20-%201%29)
![= 1 - cos^2\theta\\\\= 1 - (1 - 2 sin^2 \theta)\\\\= 2 sin^2 \theta](https://tex.z-dn.net/?f=%3D%201%20-%20cos%5E2%5Ctheta%5C%5C%5C%5C%3D%201%20-%20%281%20-%202%20sin%5E2%20%5Ctheta%29%5C%5C%5C%5C%3D%202%20sin%5E2%20%5Ctheta)
Therefore for the given equation, the answer is ![2 sin^2 \theta](https://tex.z-dn.net/?f=2%20sin%5E2%20%5Ctheta)
