Circle Calculator Area Circunference Inputs: Radius: or Diameter or Circumference: Unit: Calculate Area Result: The area of a circle with diameter 51 is 2043 Formulae: r = 25.5 d = 51 C = 160 A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference...
A radius of a circle with area 36πcm2 is 6cm, The width of the rectangle is 6cm, A diameter of the circle is 12cm, so the length of the rectangle is 24cm, The perimeter of the rectangle is 2×(6+24)=60cm. 如果一个面积为36π 平方厘米的圆的半径等于一个矩形的宽度,并且这个圆的...
The total perimeter of the un-shaded part is made up of three sides of the rectangle and the perimeter of the half-circle. The area of a half circle = ½ π r2 8 π = ½ π r2; therefore r = 4 The perimeter of the half circle is ½ 8 π = 4 π The diameter of the ...
In the figure shown, what is the area of the circular region with centerOand diameterBC? (1)BC/AB= 3/4 (2)BD= 25 选项: 答案: C 经典答疑 发起提问 提问: 点此查看答疑 这道题我选的B,因为条件2得知斜边是25,根据勾股数3 4 5,得知25刚好是5的5倍,那么短边AD即3*5=15,就是BC的长度,...

Area of Circle FormulaThe formula for the area of a circle is given by 𝜋r2, where r is the radius of the circle. The value of 𝜋, pronounced pi, is 22/7 or 3.14. Pi is the ratio of the circumference to the diameter of a circle. It is one of the widely used mathematical ...
The sector of a circle is defined as the portion of a circle that is enclosed between its two radii and the arc adjoining them. It is considered as a portion of a circle with two radii and an arc. A circle is divided into two sectors, the minor sector and the major sector where the...
