A big movie theater had 1,200 seats. 864 of the total number of the seats were sold. what percentage of the seats was sold

Reil [10]

Answer:

72%.

Step-by-step explanation:

We have been given that a big movie theater had 1,200 seats. 864 of the total number of the seats were sold.

To find what percentage of the total seats were sold we will find 864 is what percent of 1200.

$\text{ Percentage of sold seats}=\frac{864}{1200}\times 100$

$\text{ Percentage of sold seats}=0.72\times 100$

$\text{ Percentage of sold seats}=72$

Therefore, 72% of the total seats were sold.

Find the volume of a right circular cone that has a height of 9.1 m and a base with a circumference of 12.1 m. Round your answer

Orlov [11]

Answer:

$V=35.3\ m^3$

Step-by-step explanation:

-Given the cone's height is 9.1m and the Circumference is 12.1

#We use the circumference formula to calculate the radius:

$C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm$

-The volume of the cone using the radius above can then be calculated as follows:

$V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3$

Hence, the cone's volume is $35.3\ m^3$
