The area of a circle is A=πr². 
Since π is about 3.14 we can substitute that into the equation.
So A=3.14×r²
We can substitute the given radius for r.
A= 3.14 × 5²
When a number is squared, or has the two over it, we multiply it by itself. 
5 × 5= 25
A= 3.14 × 25
Simplify this and the area of the circle is about 78.5
A≈78.5

Answer:

The area of circle is 78.5 units².

Step-by-step explanation:

Area of the circle is defined by the formula A = π r²

Here r = radius of the circle and value of π = 3.14

Now by putting these values in the formula  we can get area of the circle.

A = (3.14) × 5²

A = 3.14 × 25

A = 78.5 units²

The area of circle is 78.5 units²

lorasvet [3.4K]
The ratio is:
Chlorine : Water = 1 : 10
m ( Water ) = 15 ounces
m ( Chlorine ) = x
x : 15 = 1 : 10
10 x = 15 * 1
10 x = 15
x = 15 : 10
x = 1.5 ounces
Answer:
We need to add 1.5 ounces of Chlorine for the correct ratio.
