Question

Find the area and circumfrance of a circle whose radius is 20cm (take π=3.14)

Answer 1

➡HERE IS YOUR ANSWER⬇

Radius of the circle (r) = 20 cm

Circumference of the circle

= 2 × π × r cm

= 2 × 3.14 × 20 cm

= 125.6 cm

Area of the circle

= π × r^2 sq-cm

= 3.14 × 20^2 sq-cm

= 3.14 × 400 sq-cm

= 1256 sq-cm

Answer 2

circumference of circle is 2πr
radius is 20 cm
so,
circumference of circle =2πr
=2×22/7×20
=40×3.14
=125.6cm
area of circle=πr^2
=22/7×20×20
=3.14×400
=1256cm^2
