Question

a circular piece of glass has a radius of 2.1 meters the glass sells for $7.10 per square meter what is the cost of the glass

Answer 1

Explanation:

The area of a circle is given by the formula:

A = πr^2

where A is the area and r is the radius.

Substituting the given values, we get:

A = π(2.1 m)^2 = 13.85 m^2

So the total cost of the glass with a price of $7.10 per square meter is:

Cost = Price per square meter x Total area

Cost = $7.10/m^2 x 13.85 m^2 = $98.24

Therefore, the cost of the glass is $98.24.
