Answer:
6
(4×n²) + (4×n¹) + (5×n^0) = 173
4n² + 4n + 5 = 173
4n² + 4n = 168
divide through by 4
n² + n - 42 = 0
n² + 7n - 6n - 42= 0
(n + 7)(n - 6) = 0
n = -7 or 6
but the solution is 6 since base is not negative.
Given:
The radius of the given sphere = 1 unit
To find the volume of the sphere.
Formula:
The volume of the sphere of radius r is
Now,
Substituting r=1 and π=3.14 (as given), we get
cube unit
or, cube unit
Hence,
the volume of the cube is 4.187 cube unit.
the board is 56 inches long.
how i did this was
