what owuld the area of a cicle be if 10 is the diamter

Circumference = pi * d

C = 3.14 * 10
C = ?

31.4

Right.

area or circumference?

To find the area of a circle with a given diameter, you can use the formula:

Area = π * (radius)^2

Since the diameter is given as 10, you can divide it by 2 to find the radius:

Radius = Diameter / 2 = 10 / 2 = 5

Now substitute the value of the radius into the formula:

Area = π * (5)^2 = π * 25 = 25π

So, the area of a circle with a diameter of 10 units is 25π (or approximately 78.5) square units.
