A circular piece of glass has a radius of 2.1 meters. The glass sells for $1.70 per square meter. What is the total cost of the

Vsevolod [243]

Hello!

To find the total cost, we will need to multiply the cost per square meter, by the total area. To find the area we will use the formula A=πr². We will use 3.14 for pi.

We know that 2.1 is our radius. We will square it and then multiply it by 3.14.

2.1²=4.41
4.41(3.14)≈13.85

Our area is about 13.85. Now we will multiply by $1.70 to find the total cost. This gives us about $23.55.

The total cost of the glass would be about $23.55.

I hope this helps!
