Answer:

a = 1/5 b

Step-by-step explanation:

A direct variation is given by

a = k*b where k is the constant of variation

3 = k* 15

Divide each side by 15

3/15 = k*15/15

1/5 = k

a = 1/5 b

Answer:

The area of a square with side length of 2 inches is 4 square inches.

The area of a circle with radius 1.2 inches is:

$\pi \times (1.2) ^{2} \\ = 3.14 \times 1.44 \\ = 4.5216 \: square \: inches$

That is approximately 4.5 square inches.

Hence, the area of the square (4) is less than {<} that of the circle (4.5)!
