How do you find area of a circle? could you please help?

Answer:
Step-by-step explanation:
diameter of a circle=14
π=22/7
we have to find the radius
since we have diameter it will be easy for us
radius=diameter/2=14/2=7cm
π=22/7
area of circle=22/7*7*7
remember area of circle=πr^2 this means squared
22/7*7*7=7 cancel 7
it remains 22*7=154cmsquared
area of circle =154squared
