Question

1. find the area

10 units

Explanation:

Step1: Identify the radius

The given length is the diameter, so radius $r = \frac{10}{2} = 5$ units.

Step2: Apply area formula

Use circle area formula $A = \pi r^2$.
$A = \pi \times 5^2 = 25\pi$

Answer:

$25\pi$ square units (or approximately 78.54 square units)
