the formula of area of a circle is πr^2 so,
given= d=7
r=d/2 =7/2
= πr^2 = π× (7/2)^2 = 38.48
given= d=7
r=d/2 =7/2
= πr^2 = π× (7/2)^2 = 38.48

Heya...Here is your answer --
Radius = Diameter/2
Radius = 7/2
Radius = 3.5 m
Area of circle = π×r^2
= 22/7 × (3.5^2)
= 22/7 ×12.25
= 22×1.75
= 38.5
Area of the circle is 38.5 m^2
HOPE IT HELPS...!!
