Question

if diameter of circle is 22cm than what is area

Answer 1

If diameter of circle is 22cm than what is area.

Diameter = 2 × radius, so

Radius = Diameter/2

Radius = 22/2

Radius = 11 cm

Now,

$\mathtt{area \: of \: circle = \pi\: r²} \\ \\ \mathtt{\implies \frac{22}{7} \times 11\times11 } \\ \\ \mathtt{\implies 380.38\: \: ans}$
