Answer: 1296 cm³
Step-by-step explanation:
Since, the volume of a square pyramid is,
![V = \frac{a^2h}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7Ba%5E2h%7D%7B3%7D)
Where a = side of the square base,
h = height of the pyramid,
By the given diagram,
a = 18 cm,
h = 12 cm,
Hence, the volume of the given pyramid,
![V = \frac{18^2\times 12}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B18%5E2%5Ctimes%2012%7D%7B3%7D)
![= \frac{324\times 12}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B324%5Ctimes%2012%7D%7B3%7D)
![=\frac{3888}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3888%7D%7B3%7D)
cube cm.
⇒ First option is correct.
Answer:
Step-by-step explanation:
The standard form of a circle is
where h and k are the center of the circle and r is the radius. Our center is located at (0, 1), so h = 0 and k = 1. Going from the center straight up of down we have to move 2 units to get to a point on the outside of the circle, so r = 2. Filling in our equation:
which simplifies a bit to
![x^2+(y-1)^2=4](https://tex.z-dn.net/?f=x%5E2%2B%28y-1%29%5E2%3D4)
Answer:
x=10
Step-by-step explanation:
First add 7 on both sides
6x-7=53
+7 +7
6x=60
Divide 6 on both sides
x=10
Ok! So first, 2 hours are 120 minutes and 55 + 35 = 90
120 - 90 = 30
So the answer is A. Cindy spends 30 minutes on History
Hope it helps!
The correct answer is y = -x +1
