The class was taught on how to find the surface area of prisms, pyramids, cylinder and cones. They share an specific letter for their formula,
prism= PH+2B. The P stands for perimeter of the base, and H stands for height. The B stands for the area of the base.
Other surface areas for these shapes may include half, pi or radius squared.
We learned about rhombus. Rhombus is a parallelogram that has 4 congruent sides. If a parallelogram is a rhombus, then it’s diagonals are perpendicular.
We talked about trapezoids. A trapezoid is a quadrilateral with one pair of parallel sides. If the trapezoid is isosceles, then each pair of base angles are congruent.
The 3- dimensional shapes volume. Discussion of the pyramid, sphere, prisms, and cones. Volume is the quantity of three dimensional space that a shape contains. Formula for pyramid is 1/3bh. B is the area of the base and h is the height of the pyramid. A sphere volume is v=bh.
I’m late but that week we learned about rectangles. Rectangles are parallelograms with 4 right angles. It has two sets of parallel sides that are congruent. Consecutive angles are supplementary, diagonals bisect each other. If a parallelogram is a rectangle, then it’s diagonals are congruent. If the diagonals Of a parallelogram are congruent, then the parallelogram is a rectangle.
angles of a polygon with n sides is (n – 2)180. The measure of each interior angle of an equiangular n-gon is. If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360 degrees. a parallelogram is a quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
My spring break was somewhat decent, I had track practice. Gotta improve on a whole lot of stuff that was horrible last season. I got my wisdom teeth pulled (all 4 of them). It was one THE MOST painful experiences of my life because I couldn’t do nothing afterwards, I couldn’t eat regular food for a while. I wasn’t stuck eat mash potatoes and ice cream for a while, it was hard because I couldn’t let anything get into the extraction point where my teeth were pulled from. Til this day I still have problem with that, because if I don’t keep it clean, The food can get stuck and clog up the extraction and get effected, That pretty much sums up my 2019 spring break.
A diameter of a circle is a chord that passes through the center and has both ends on the circle made up of collinear radii., a diameter is a special kind of chord!
