The area of a circle is given by the formula:
A = Ttr2 where r is the radius of the circle.
What is the exact area of a circle with a diameter of 10 cm?


Respuesta :

Answer:

A = 25π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( where r is the radius )

Here diameter = 10, thus r = 10 ÷ 2 = 5, then

A = π × 5² = 25π cm²
