Answer to: Calculate the area of a circle (in m2) with a diameter of 60 mm. By signing up, you'll get thousands of step-by-step solutions to your...
Circles are the two-dimensional shapes in which a central point contains a fixed distance from a round closed path and, this distance is uttered as the radius of the circle. The area of a circle is basically the space coverage by the circle on a plane. ...
where R is the radius of the circle The area of the circle area (A)=πR2 and, circumference of the circle (C)=2πR Answer and Explanation: Given that the radius of a circle is 12 cm. R=12 cm The diameter of a circle has the double length as com...
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...
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 ...
How to divide the circumference of a circle equally? First you calculate the circumference of the circle using the standard formula C=pi x D, Where C is the circumference, D is the Diameter of your circle (measured across the widest part of the circle) and pi is a known constant...
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,...
