Question

the diameter of a circle is 2 find its area

Answer 1

hello mate !...


We know area of circle

$= > \pi \: r {}^{2} \\ \\ \\ \\ given... \\ \\ d = 2 \\ \\ r = \frac{d}{2} \\ \\ r = \frac{2}{2} = 1 \\ \\ area \: of \: circle = 3.141 \times 1 {}^{2} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.141 \: m {}^{2}$


HOPE IT HELPS U

Answer 2

Find the radius:

Radius = Diameter ÷ 2

Radius = 2 ÷ 2 = 1 unit

Find the area:

Area = πr²

Area = π(1)² = π = 3.14 units²

Answer: The area is 3.14 units²
