Find the height of a cone with a diameter of 12 m and whose volume is 133 m. A. 2 m
B. 9 m
C. 3 m
D. 1 m

D

Step-by-step explanation:

Here, we want to get the height of the cone

radius = diameter/2

r = 12/2 = 6 m

To get this, we use the formula for the volume

V = 1/3 * pi * r^2 * h

133 = 1/3 * 3.142 * 22/7 *6^2 * h

h = 1.12 m

idk

i know the way

and

idk

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
