Question

the diameter of a circle is 14cm its area is ___________cm2​

Answer 1

Answer:154 cm^2

Step-by-step explanation:

Radius(r) Of a circle=half of diameter

Radius(r)=1/2(14)=7cm

Area Of circle=$\pi r^{2}$

Area of circle=$\pi$(7)^2

                       =(22/7)(7)(7)

                        =154 cm^2 ANS

Answer 2

r=d/2

area of circle = πrsq

22/7×7sq

22/7×49

22×7

154
