Question

A circle has a diameter of 14 cm, then area of circle is​

Answer 1

Answer:

154cm²

Step-by-step explanation:

diameter= 14cm

radius= 7cm (diameter= 2x radius)

area of a circle= 22/7 × r²

                        = 22/7 × 7 × 7

                        = 22×7

                        =154 cm²

Answer 2

Answer:

$154 \: {cm}^{2}$

Step-by-step explanation:

Diameter = 14 cm

Radius = Diameter/2

Radius,(r) = 7 cm

Area of circle = π × r × r

= 22/7 × 7 × 7

= 22/7 × 49

= 22 × 7

= 154

Therefore, the area of the circle is 154 cm.square.
