Answer:

A = 6.25π

Explanation:

Area of a circle:

A = πr²

Given:

d = 5

To find r, divide d by 2:

r = d/2

r = 5/2

r = 2.5

Area of a circle:

A = πr²

A = π2.5²

A = 6.25π

Answer:

25π/4 square meters

Explanation:

The area of a circle is given by the formula ...

A = πr² . . . . . where r is the radius of the circle.

The radius is half the diameter, so is (1/2)(5 m) = 5/2 m. Using this in the area formula, we find the area to be ...

A = π(5/2 m)² = (25/4)π m²

The area of the circle is 25π/4 square meters.

__

As a decimal, that is 6.25π square meters.
