Question

A circular piece of glass has a radius of 0. 8 meters. The glass sells for $4. 60 per m². What is the total cost of the circular piece of glass? Use 3. 14 for pi. $2. 01 $9. 24 $23. 11 $36. 98.

Answer 1

The cost of the circular glass piece will be equal to $9. 24

What will be the cost of the circular glass piece?

It is given that

The radius of the circular glass piece $r= 0.8 meters$

The selling price of glass per square meter = $4. 60

Now find the area of the circular glass piece

$A= \pi r^{2}$

$A=\pi \times (0.8)^{2}$

$A=2.01 m^{2}$

Now cost of the glass piece =

$=Area \times selling price of glass pieces per square meter area$

$= 2.01\times4.0=9.24$

Thus the cost of the circular glass piece will be equal to $9. 24
