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=<span>πr</span>². 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!
In maths, Distance is described as the quantity of space between two points, and further calculation can be defined as follows:
Given Expression:
![5x + 2 = 30\\\\2(x + 5) = 30\\\\5(x + 2) = 30\\\\2x + 5 = 30](https://tex.z-dn.net/?f=5x%20%2B%202%20%3D%2030%5C%5C%5C%5C2%28x%20%2B%205%29%20%3D%2030%5C%5C%5C%5C5%28x%20%2B%202%29%20%3D%2030%5C%5C%5C%5C2x%20%2B%205%20%3D%2030)
To find:
distance=?

Answer:
A) 0.38
Step-by-step explanation:
By SOH CAH TOA, the <em>sine of an angle is its opposite side divided by the hypotenuse</em>.
<em>The opposite of ∠C is 5, and the hypotenuse is 13</em>.
So, sin(C) = 5/13 ≈ 0.38.
