Question

Which expression represents the cost of the mulch based on the radius of the circle?

Answer 1

we have

$m(x)=\pi x^{2}-2\sqrt{2}x^{2}$ ---------> equation 1

$g(m)=1.50m$ ---------> equation 2

To represent the cost of the mulch based on the radius of the circle

Substitute equation 1 in equation 2

$g(x)=1.50*[\pi x^{2}-2\sqrt{2}x^{2}]$

therefore

the answer is the first option

$1.50*[\pi x^{2}-2\sqrt{2}x^{2}]$
