katrin [286]

Answer:

option a)

y = m(0.5) + 1.8

Step-by-step explanation:

Equation

<h3>y = mx + c</h3>

represent the equation of straight line

here m = gradient of straight line

         c = y-intercept

First find the gradient of the graph

<h3>m = y2 - y1 / x2 - x1</h3>

    = 4 - 3 / 4 - 2

    = 1 / 2

Put the values in the equation of straight line

y =mx + c

4 = 1/2(4) + c

c = 2

y = 1/2x + 2

which is approximately equal to y = 0.5x + 1.8

katen-ka-za [31]
To get the amount of soil required to fill the urn, we need to get the volume of the urn. Given that the urn is cylindrical in shape, the volume will be given by:
V=πr^2h
radius=1.5 ft
height=3 ft
thus;
V=π*1.5^2*3
V=21.2058 ft^3
The answer is V=21.2058 ft^3
