Then, using a square, draw a line that is exactly 90 degrees to the chord pointing towards the center of your circle. Make it a little longer then where you think the center of the circle resides. Do this for all of your chords. Step 3: The Center Is the Point Where They Intersect...
aMaybe your maths teacher has already taught you how to find the centre of a circle(圆). It isn’t easy to learn and it takes some time to do so. Here’s a way.please put a corner of a square piece of the circumference of a given circle,and you will see the two sides of the...

Find the central angle of a circle with an area of {eq}74400 {/eq} sq. units and a radius of {eq}75 {/eq}. Let {eq}\pi = 3.14 {/eq}. Area of a Circular Sector: A sector is very similar to a slice of pie or pizza where the vertex is ...
If a square is inscribed in a circle find the ratio of the areas of the circle and the square - Given:A square is inscribed in a circle. To do:We have to find the ratio of the areas of the circle and the square.Solution:Let $r$ be the radius of the ...
A circle is a round, symmetrical shape with no corners or sharp edges where each point along its edge is equidistant from the center. A circle has many properties, such as the radius, diameter, circumference, and area. Theradiusis the length of a straight line from the center to any poin...
Calculate the area of the square first by multiplying its side length, s, by itself: area=s2 For example, suppose the side of your square is 10 cm. Multiply 10 cm × 10 cm to get 100 cm2. Step 2 Calculate the circle's radius, which is half the diameter: ...
The sector of a circle is a partition of that circle. A sector extends from the center, or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought
