Circumference, Volume and Area

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 wrong formulas are being used.

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

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)
