Answer:

area of a circle is = 78.5units²

Step-by-step explanation:

to evaluate for the area of a circle  whose diameter =  10

π = 3.14

recall that the area of a circle is = πr²

since we were given diameter

note that diameter = 2 x radius

radius = diameter / 2

radius = 10/2

radius = 5units

area of a circle is = πr²

area of a circle is = 3.14 x (5)²

area of a circle is = 3.14 x 25

area of a circle is = 78.5units²
