# Volume 5/7/19

The past week we learned about solving 3-dimensional shapes for their volume. Volume is the amount of space a 3-dimensional object has which is measured in cubic units. The volume of a circular cone is V=1/3Bh, or V=1/3(pi)r^2h, where B is the area of the base, h is the height of the base, and r […]

# 5/1/19 prisms/cylinder/pyramid/cones

This week we learned about prism , cylinders, pyramids, and cones. The surface area (S) of the right prism is S=L+2B, where L is its lateral area and B is the area of the base. A prism is a figure that has equal sides with a parallelogram. The formula for the prism would be S=Ph+2B, […]

# Rhombi and Trapezoid 4/23/19

A rhombus is a parallelogram that has all 4 sides congruent. If a parallelogram is a rhombus then it’s diagonals are perpendicular. In a rhombus it’s diagonals bisects a pair of opposite angles. If the diagonals of a parallelogram are perpendicular then the parallelogram is a rhombus. Also if one diagonal of a parallelogram bisects […]

# Study Guide 4/18/19

For the first problem, you have to find your angles and measurement. You know that NK is 17 because 34/2= 17. You know that JL is 22 because 11+11=22. Kl is 20.248 because you have to use Pythagorean Theorem which will be 17^2+11^2=410 and 410 squared is 20.248. In a rhombus opposites are congruent to […]

# 4/12/19 Rectangles

This week we learned about rectangles. When you have a rectangle opposite sides should be congruent to each other. Also diagonal from one side to the other should be congruent. A rectangle is also a parallelogram with a right angle. The entire rectangle would equal up to 360 degrees. To find out if your shape […]

# 4/5/19 polygon and parallelogram

When learning about polygon you can find the interior or the exterior. The formula that you would use is (n-2)180. The n in the equation stands for the number of sides. Convex is the direction of the angle points outside the shape. Concave is the direction of angle that points inside of shape. For polygons […]

# Spring break 3/31/19

During spring break I enjoy the time that we had out of school. All week I had to babysit my two little cousins. We played Fortnite and went to the gym to play basketball. I didn’t go out of town because I had basketball practice. We have basketball practice on the weekends and we were […]

# 3/14/19 major grade

The first 1-4 questions you have to identify the angles as minor, major, or semicircle. Also you have to find each measure. They give you measure DC which is 80. Then you are left to find ED and AE. You would subtract 180-80 because AEDC are all equal to 180. Then you would get 100 […]
