The radius of a circle is 4 m. Find its area in terms of π π.

wlad13 [49]

Answer:

16π

Step-by-step explanation:

Given:

$\text{Radius of circle}: 4 \ \text{m}$

Formula:

$\text{Area of circle} = \pi r^{2}$

Replace the radius in the formula:

$\implies \text{Area of circle} = \pi (4)^{2}$

Evaluate the area:

$\implies \text{Area of circle} = \pi (4)(4)$

$\implies \text{Area of circle} = 16\pi$

Since the question says to determine the area in terms of π, the final answer is 16π.
