area of circle(A′)=πD24 whereDis the diameter of the circle The diameter of a circle is double in magnitude as compared to the radius of the circle. Answer and Explanation:1 Given that a circle is inscribed in a square wi...
Area of a circle using the radius Given the radius of a circle, the formula for calculating the area of a circle states that: Area of a Circle = πr2 square units A = πr2 square unitsWhere A = the area of a circle. pi (π) = 22/7 or 3.14 and r = the radius of a circle...
5. Draw a circle in a square, and the area of the circle is12.56cm^2 then the area of the square is( )cm^2 at least (至少).A. 12.56B. 14C. 16D. 20 相关知识点: 试题来源: 解析 C. 16 已知圆的面积为12.56平方厘米,根据圆的面积公式,可求得圆的半径为2厘米。由于圆内切于正方...
<p>To solve the problem, we need to find the ratio of the perimeter of a circle and a square when their areas are equal.</p><p>1. <strong>Define the Variables</strong>: Let the radius of the circle be \( r \) and the side length of the square be \( a
Next, we roll the circle across a straight line, starting from the mark until it completes one cycle: If we measure the length of the straight line, we are also measuring the perimeter of the cutout circle. And in this measurement, we get a number that is close to the constant !

Note: Max could have estimated the area by: 1. Calculating a square hole: 0.4× 0.4 = 0.16 m2 2. Taking 80% of that (estimates a circle): 80% × 0.16 m2 = 0.128 m2 3. And the volume of a 1 m deep hole is: 0.128 m3And something interesting for you:See...
