- 3D - sphere! 0 0 The circle has a curved side We typically think of a shape as a closed contour For mathematical objects in more dimensions, see list of mathematical shapes Since a rectangle is comprised of four right angles, the diagonal that cuts through the shape will create a right triangle, so you can apply the Pythagorean theorem Since a rectangle is comprised of four right angles, the ...
- Answer: The coordinates of centroid are given as (5, 4.58), or the centroid is 4.58 units from the side whose length is 5 units.
- The centroid of a trapezoid can be found out by using the formula given below: x = b + 2 a 3 ( a + b) × h . Here, h= height of the trapezoid, a, b= length of the parallel sides. These are also the important Questions for CBSE Class 10 Math Chapter 9 - Some Applications of Trigonometry.
- Segment of circle and perimeter of segment: Here radius of circle = r , angle between two radii is " θ" in degrees. Area of the segment of circle = Area of the sector - Area of ΔOAB. Area of the segment = ( θ /360) x π r 2 + ( 1 /2) x sinθ x r 2. Perimeter of the segment = (θ π r / 180) + 2r sin (θ/2). Chord length of the circle ...
- We need to calculate the midpoints of the line PQ, which is F, and the slope to find the equation of the perpendicular bisector. Step 1: Lets calculate the midpoint of the line which is the average of the x and y co-ordinates. Midpoint of a line = x1+x2/2, y1+y2/2. Midpoint of PQ =
