The variables a and b are positive numbers. drag and drop each coordinate point to match the correct quadrant.

Hence,

Quadrant I     ( a , b)

Quadrant II   ( -a , b)

Quadrant III   ( -a , -b)

Quadrant IV ( a , -b)

Step-by-step explanation:

There our four quadrant divided by the x-axis and y-axis.

So the variables according to the quadrant are given below.

Quadrant I : Both the coordinates are positive.

Quadrant II : x-coordinate is negative and y-coordinate it is positive.

Quadrant III : x-coordinate is negative and y-coordinate it is negative.

Quadrant IV : x-coordinate is positive and y-coordinate it is negative.

Hence,

Quadrant I     ( a , b)

Quadrant II   ( -a , b)

Quadrant III   ( -a , -b)

Quadrant IV ( a , -b)

We will need calculate the area of the top, the base and  sides.
area of the top=πr²
area of the base=πr²
area of the side: 2πrh
surface area of a cylinder: area of the top + area of the base +area of the side
surface area of a cylinder=πr²+πr²+2πrh=2πr²+2πrh=2πr(r+h)

Data:
r=1.5 m
h=1.5 m

surface area of this cylinder=2π(1.5m)(1.5 m+1.5 m)=3π m*(3 m)=9π m².

9π m²
