Answer: Area of Circle Formula Suppose a circle has a radius ‘r’ then the area of circle = πr2 or πd2/4 in square units, where π = 22/7 or 3.14, and d is the diameter. Area of circle can be calculated by using the formulas: Area = π x r2, where ‘r’ is the radius. Reply
Answer: 22/7×d²/4 Step-by-step explanation: diameter = d Therefore radius = d/2 Area of circle= 22/7×r² =22/7(d/2)² =22/7×d²/4 Reply
Answer:
Area of Circle Formula
Suppose a circle has a radius ‘r’ then the area of circle = πr2 or πd2/4 in square units, where π = 22/7 or 3.14, and d is the diameter. Area of circle can be calculated by using the formulas: Area = π x r2, where ‘r’ is the radius.
Answer:
22/7×d²/4
Step-by-step explanation:
diameter = d
Therefore radius = d/2
Area of circle= 22/7×r²
=22/7(d/2)²
=22/7×d²/4
