We need to solve for the radius
circumference = radius * 2 * PI
radius = circumference / (2*PI)
radius = 4.5 / ( <span> <span> <span> 6.2831853072 </span> </span> </span> )
radius = <span> <span> <span> 0.7161972439 </span> </span> </span> feet
Formula for cylinder volume:
<span>Volume = </span><span>π • r² • height</span>
Volume = <span>π • (</span><span> <span> <span> 0.7161972439)^2 * 12
</span></span></span>Volume = PI * <span><span>0.5129384922 </span> * 12
Volume  </span><span><span><span>19.3373255857 </span> cubic feet
</span> </span>

Gwar [14]

Answer:

y=mx+c

Step-by-step explanation:

A linear equation means the equation of straight line.

The formula for equation of straight line in slope intercept form is y=mx+c

where, m is the slope of line and c is the y intercept

The formula for equation of straight line in double intercept form is x/a+y/b=1

The formula for equation of straight line in normal form is xcos α + y cos α=p

There are more formulas bur assuming you are asking for the general representation of the straight-line equation, it is y=mx+c.
