Find the area of circle with diameter 28cm?

Answer»

ANSWER:

Step-by-step explanation:

To FIND the AREA first we need to find the radius of the circle from the diameter.

Diameter = 28 cm

Radius = diameter/2

= 28/2

= 14 cm

Area of circle = Π r ²

= (22/7) ⋅ (14)²

= (22/7) ⋅ 14 ⋅ 14

= 22 ⋅ 2 ⋅ 14

= 44 ⋅ 14

= 616 cm²
