Question

a circles radius is 25 centimeters. what is the circles area? use 3.14 or a calculator button for pi and provide an answer accurate to the nearest tenth. r = 25 cm

Explanation:

Step1: Recall circle area formula

The area of a circle is given by $A = \pi r^2$, where $r$ is the radius.

Step2: Substitute radius value

Substitute $r = 25$ cm into the formula:
$A = \pi \times (25)^2$

Step3: Calculate radius squared

$25^2 = 625$, so $A = 625\pi$

Step4: Compute numerical value

Use $\pi = 3.14$:
$A = 625 \times 3.14 = 1962.5$

Answer:

1962.5 square centimeters
