Answer:

The area of this circle is 78.5

Step-by-step explanation:

The area of a circle can be calculated with the equation πr². r stands for "radius", the distance between the center of the circle to any point of its edge which also equals to half of a circles diameter. Since the diameter of this circle is 10 in., its radius is

[tex]r = d/2 = 10/2 = 5\\[/tex]

Then, we use this to find the area

Area =[tex]\pi r^2=\pi (5)^2=25\pi=78.5[/tex] (rounded to the first decimal place)
