R=4;h=12 find the volume

192π square units

Step-by-step explanation:

The volume of a cylinder is π*r^2*h. Think of it as the area of the circle base, which is πr^2, times the height, h.

with r=4 and h=12,

The answer is π*4^2*12=16*12π=192π

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
