Question

HELP ASAP PLEASE!!))

Find the area (in square units) of the circle with center O and radius 12 units long. Round your answer to the nearest whole number. (Enter only a number as your answer .)

Answer 1

To calculate the area of a circle, we use the formula : $\pi r^{2}$, where r is radius.

We replace the numebrs : 144$\pi$ = 452,389342.... = 452 (rounded)

So, the area of this circle is 452 (and whatever units)

Answer 2

Answer:

Area of circle = 452 units²

Step-by-step explanation:

We can use the following formula to calculate the area of a circle:

Area = π r²

where r = radius of circle (12 units)

Substituting into the formula:
Area = π × (12)²

        = π × 144

        = 452.39

        = 452 units²       (rounded to the nearest whole number)
