Question

find area of circle radius =3.5 cm explain properly​

Answer 1

Answer:

The area of the circle is 38.5 cm².

Step-by-step explanation:

The radius of the circle is 3.5 cm

Area of the circle is given by the formula = πr²

Substituting r= 3.5 cm

$\pi r^{2} = \pi (3.5)^{2} = \frac{22}{7} X 3.5 X 3.5 = 11X3.5 = 38.5 cm^2$

Answer 2

Given: r=3.5,

Area of Circle = πr², π=22/7

=22/7×(3.5)²

=38.5
