Answer:
2
Step-by-step explanation:
(3/4)/(9/2)=1/6 tank of gas used every hour.
1/6*12=2 tanks of gas used in 12 hours.
Answer:
110x5019.2 is equal to 552169.2
The formula for the area of a circle is A = pi x (radius^2).
We need the radius of the circle in order to use the formula. The radius is equal to 1/2 of the diameter of the circle. The radius goes from the center to one side of the circle, whereas the diameter touches two sides of the circle and goes through the center.
radius = 6 / 2 = 3 units
Remember that a semi-circle is equal to 1/2 of a full circle. So we need to find the area of the whole circle and divide it by 2.
A = pi x 3^2
A = 9pi
A = 4.5pi = 14.13 units^2
Hope this helps! :)
Answer:
option C : 3pi/4
Step-by-step explanation:
Measure of given arc= 135 degree
To convert degree to radians we multiply by ![\frac{\pi }{180}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20%7D%7B180%7D)
we multiply 135 by ![\frac{\pi }{180}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20%7D%7B180%7D)
![135 * \frac{\pi }{180}](https://tex.z-dn.net/?f=135%20%2A%20%5Cfrac%7B%5Cpi%20%7D%7B180%7D)
Then we simplify it
![\frac{135\pi}{180}](https://tex.z-dn.net/?f=%5Cfrac%7B135%5Cpi%7D%7B180%7D)
divide top and bottom by 5
so we will get ![\frac{27\pi}{36}](https://tex.z-dn.net/?f=%5Cfrac%7B27%5Cpi%7D%7B36%7D)
Again divide both sides by 9
so we will get ![\frac{3\pi}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cpi%7D%7B4%7D)
Answer:
The answer is D. 2
Step-by-step explanation:
exponential form
exponents equal
move constant to the right
subtract the number
divide both sides by 2
