Question

The diameter of a circle is m. What is the area

Answer 1

`(\frac{{m}^(2) }{4} )\pi`

Explanation:

we can find the radius from the diameter by dividing the diameter by 2 (radius is half the diameter)

the formula for the area of a circle is r²π (with r being radius) but since we must use diameter we have to replace r with (m/2)

this gives us our new formula of (m/2)²π, which simplifies to (m²/4)π

that is the answer
