Finding area using diameter

WebThe radius of the circle is given. That means we can easily find the diameter by doubling it. Plug the value of diameter into the formula to get the area. Therefore, the area of the circle is about 19.64 19.64 c {m^2} cm2. Example 5: Calculate the area of the circle below using radius r r and diameter d d. WebWhen the area of a semicircle is given, the radius and the diameter can be calculated using the same formulas: Area of a semicircle with radius = πr 2 /2; Area with diameter = πd 2 /8, where 'r' is the radius, and 'd' is the diameter. We can substitute the known value of the area in these formulas and find the missing radius and diameter.
