6.G.11Area of polygons on a coordinate plane
To find the area of the
given polygon, count the number of
unit squares
inside the polygon.
To find the area of the given
polygon, count the number of unit squares in the length and width. Then
use the formula to calculate the
area.

66 sq units
A coin has a circumference of 12.56 cm. What is the radius of the coin?
A circle painted on the playground has an area of 314 square feet. What is the radius of the circle?

Jonathan ordered a pizza with an area of 63.585 square inches. Marie ordered a pizza with a circumference of 28.26 inches. Whose pizza has the greater diameter? Show your work and explain your reasoning.
Both have the same diameter of 9 in.
Prism Cone
Cylinder Pyramid
2 parallel & congruent

Determine the volume of a box 2 m long, 2 m tall and 1 m wide?
What is the volume (in terms of Л) of a cylinder with a radius of 5cm and a height of 8 cm? V = πr²h V = 200π cubic cm
V = lwh V = 4cubic meters
Calculate the surface area of the following shapes.
SA = Area of 2 triangles + Area of 3 rectangles
Area of Triangle = 24 sq in.Area of Rectangles = 70, 56, 42
SA = 2 * 24 + 70 + 56 + 42SA = 216 sq in.
SA = 2lw + 2lh + 2whSA = 2(2●5) + 2(2●7) + 2(5●7)SA = 20 + 28 + 70SA = 118 sq ft
Calculate the surface area of the following shapes.
SA = Area of 2 circles + Area of rectangle
Area of circle = 50.24 mArea of rectangle = 236.13 m
SA = 2 * 50.24 + 236.13
SA = 336.61 sq m
The sum of the interior angles of a quadrilateral is 360°
In parallelogram ABCD, m∠C = 60˚ and m∠D = 120˚. Find the measure of the angle opposite ∠C.
In quadrilateral EFGH, m∠E = 115˚, and m∠F = 135˚, and m∠G = 45˚. Find the measure of the ∠H.
Hypotenuse = c
Leg = a or b
Leg = a or b
a² + b² = c²
Longest side of the

xThe hypotenuse of a right triangle is 12 inches and
one of its legs is 7 inches. Find the length of the other
leg. x = length of the missing leg
a² + b² = c²
a² + b² = 12²
7² + x² = 12²
49 + x² = 144
x² = 95

x ≈ 9.7 inches
The measures of three sides of a triangle are 15 inches, 8 inches and 17 inches. Determine
whether the triangle is a right triangle.
Longest side = Hypotenuse
c = 17 inches
289 = 289
A triangle with sides of 15 inches, 8 inches, and 17 inches is a right triangle.
a = 15 inches
b = 8 inches
a² + b² = c²
15² + 8² = 17²?
225 + 64 = 289?
