Question

Find the area of the circle whose diameter is 6.2cm.
please solve this question​

Answer 1

Area of circle = πr²

For radius.,

r =diameter/2 = 6.2/2 =3.1cm.

Now,

Area of circle = πr²

( value of π = 22/7)

= 22/7 ★ 3.1 ★ 3.1

=22/7 ★9.61

=30.19cm².

Answer 2

Answer:

here

diameter (d)=6.2

area(a)=?

We know that

area(a)=^d

3.14×6.2

=19.468 cm2
