## Section

What is area?the number of square units needed to cover a given surface
What is circumference?the distance around a circle
what is a diameter?a line segment that passes through the center of a circle and has endpoints on the circle ,or the length of that segment
What is parallelogram?a quadrilateral with two pairs of parallel sides
What is a perimeter?the distance around a ploygon
What is the volume?the number of cubic units needed to fill a given space
What is a square?a rectangle with four congruent sides
What is a raduis?a line segment with one endpoint at the center of a circle and other endpoint of the circle ,of the length of the segment
What is a rectangle?a parallelogram with four right angles
What is a prism?a polyhedron that has two congruent polygon shaped bases and other faces that are all parallelogram
What is a triangle?a three -sided polygon
What is a trapezoid?a quadrilateral with exactly one pair of parallel sides
Steps for Area of a circle 1)use a compass to draw a circle 2)fold circle 3)unfold circle 4) cut out
Steps for volume1)find the base 2)find the volume
Steps for surface area1)Identify base 2)Identify base
Circumference of circleC=pi d and C=2 pi r
Area of circleA=pi r 2
TriangleA=1/2 b*h
RectangleA=l*w
ParallelogramA=b*h
TrapezoidA=1/2 h(b 1 +b 2)
surface area of prismS=ph+2b
Volume of prismV=b*hv
