Step-by-step explanation:
area=πr²
radius=2
in terms of pi= π2²
ans= 4π
Given:
Side length of a cube is
units.
To find:
The equation for the volume of the cube.
Solution:
We know that, the volume of a cube is:

Where, a is the side length of the cube.
Putting
, we get

![[\because (ab)^m=a^mb^m]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28ab%29%5Em%3Da%5Emb%5Em%5D)
![[\because (a^m)^n=a^{mn}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%5Em%29%5En%3Da%5E%7Bmn%7D%5D)
So, the volume of the cube is
cubic units.
Therefore, the correct option is A.
Answer:
f(3) = 3
Step-by-step explanation:
f(x) = (1/7)(7x)
f(3) = (1/7)(7×3)
f(3) = (1/7)(21)
f(3) = 3
Answer:
(2a−1)(2a−1)
Step-by-step explanation:
Factor 4a2−4a+1
4a2−4a+1
=(2a−1)(2a−1)
The value is 11.
121^1/24 is actually square of 121^1/12
so x= square of 121 = 11
