When the circumference is 125.6, what is the diameter?
C = πd
125.6 = 3.14d
C = π (r) (r)
125.6 = 3.14 (r)(r)
C = 2 π r
125.6 = 6.28r
C = 1/2 bh
125.6 = 1/2 (bh)
If the circumference is 157, what is the radius?
C = πd
157 = 3.14d
C = 2πr
157 = 2(3.14)r
157 = 6.28r
C = π (r) (r)
157 = 3.14 (r2 )
C = πd
C = 3.14 (157)
How would you find the area of this trapezoid?
A = 1/2 (12 + 7) 15
A = 1/2 (7 + 6) 15
A = 1/2 (15 + 12) 6
A = 1/2 (12 + 15) 7
How would you find the Area of this Trapezoid?
A = 2 (9 + 4)(6)
A = 1/2 (6 + 9) (4)
A = (9 + 4) • 6
A = 1/2 (4 + 9)(6)
Use a calculator to determine which is larger.
A = π (72) or Area of a Trapezoid A = 1/2 (7 + 7 ) (2)
The area of the circle is larger
The area of the trapezoid is larger
They both have the same Area.
Use a calculator to determine which is larger. Area of a Circle where A = π (102 ) or Area of a Trapezoid where A = 1/2 (10 + 30) (2)
The Area formulas are not correct.
The areas of both are the same.
The area of the trapezoid is larger
The area of the circle is larger
If a diagonal line is drawn between two corners, the AREA of one trapezoid will be . . .
A = 1/2 (5 + 15) (7)
A = 1/2 (7 + 10) (6)
A = 1/2 (6 + 10) (5)
A = 1/2 (15 + 7) (6)
To find the Volume, use the formula V = Bh. What shape is the Base, and the formula for that Base?
Rectangular Base. Area of the Base is l x w.
Triangular Base. Area of the Base is 1/2bh
Triangular Base. Area of the Base is 1/2 (b1 + b2 )h
Retangular Base. Area of the Base is πr2
To find the Volume, use the Formula V = Bh. What shape is the Base? What is the formula for that Base?
Triangular Base.
A = 1/2bh
Trapezoid Base.
A = 1/2 (b1 + b2 ) h
Find the Volume of this Prism. Use the formula V = Bh. What shape is the Base and what is the formula for that Base.
Base is a Rectangle.
A = l x w
Base is a Trapezoid. A = 1/2 (b1 + b2 ) h
Base is a Triangle. A = 1/2 bh
Base is a Triangle. A = l x w
The volume of this box is 240 cubic inches. V = Bh. The Base measurements are 10 x 12. What is the height?
h = 3 inches
h = 4 inches
h = 2 inches
h = 1.5 inches
Which is larger? Area of a Circle A = π (3) (3) or Area of a Trapezoid 1/2 (16 + 4) (9)
Area of the Trapezoid is larger.
Area of the Circle is larger.
Both Areas are the same.

The height of the triangle is 21. The diameter is 18. Find the total Composite Area.
A = 1/2 (21) (9)
A = 3.14 (18) (18)
A = 1/2 (18) (21)
A = 3.14 ( 18) (18)
A = 1/2 (18) (21)
A = 3.14 (9) (9)
A = 1/2 (21) (9)
A = 3.14 (9) (9)
Carmen bought 5 identical books and a package of colored pencils. The cost of the pencils was $9.99. She spent a total of $24.99. How much was each book?
5 + 9.99 = 24.99
9.99x + 5 = 24.99
9.99 - 5x = 24.99
5x + 9.99 = 24.99
The circumference of a circle is 69.08. Find the radius.
C = π (r) (r)
69.08 = 3.14 (r) (r)
C = 2 π r
69.08 = 2 (3.14) r
C = 2 π d
69.08 = 2 (3.14) d
C = 2 π r
3.14 = 2 (69.08) r
