How do you figure length of a radius?
The radius of a circle is half of its diameter
Which solid figure has a face that is a circle?
It the circular face is uniform along it's length then the shape is a cylinder.
What is the definition of the area of a figure?
Depends on the figure: square/rectangle is length time height Triangle is .5base times height Circle is pi r^2
A round figure whose surface is at all points equidistant from the center is called what?
A circle is a round figure with all points equidistant from the center. Radii of equal length is the main defining characteristic of a circle.
What is the length of a circle known as?
The length around a circle is the circumference The length across a circle is the diameter
How do you figure length of a radius?
The radius of a circle is half of its diameter
What is the definition of two dimensional?
A figure that has length and width but not height (ie, a plane figure such as rectangle or circle)
Is a circle a two dimensional figure?
Yes, as it has length and width, which just happen to be equal.
A figure is made up of square with a side length of 8 cm and a circle inside it with the same diameter as the length of the square. Find the area of the composite figure. Show your solution?
64
How do you figure out the diameter of a circle?
Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.
Which solid figure has a face that is a circle?
It the circular face is uniform along it's length then the shape is a cylinder.
Why is the circle a two dimensional figure?
A circle is two dimensional because the two dimensions are width and length. 3 dimensional would be width, length and depth but since you can just write it on paper, it has no depth.
What geometric figure has a measurable length?
Any two dimentional geometric figure has a measurable length. This measurement is called circumference. This is also called a plane figure. Examples of plane figures with measurable lengths are: triangle, square, circle, and rectangle.
What is the equation on perimeter?
The perimeter of a plane figure is the length of its boundary. Thus the perimeter of a rectangle of length L and width W is 2L + 2W. The perimeter of a circle is the length of its circumference.
What is the definition of the area of a figure?
Depends on the figure: square/rectangle is length time height Triangle is .5base times height Circle is pi r^2
A round figure whose surface is at all points equidistant from the center is called what?
A circle is a round figure with all points equidistant from the center. Radii of equal length is the main defining characteristic of a circle.
What is the length of a circle known as?
The length around a circle is the circumference The length across a circle is the diameter
