Question

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

Answer 1

16π

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.
