Answer:
the area of the circle with diameter 28 cm is 615.44 square centimeters.

Explanation:

he area of a circle can be calculated using the formula:

A = πr^2

where A is the area of the circle, π (pi) is a constant approximately equal to 3.14, and r is the radius of the circle.

We are given the diameter of the circle, which is 28 cm. We can find the radius by dividing the diameter by 2:

r = d/2 = 28 cm/2 = 14 cm

Now we can substitute the value of the radius into the formula for the area:

A = πr^2 = π(14 cm)^2

Using the value of pi as 3.14, we get:

A = 3.14 x (14 cm)^2

A = 3.14 x 196 cm^2

A = 615.44 cm^2

Therefore, the area of the circle with diameter 28 cm is 615.44 square centimeters.
