Unit 5 Review

Front

Calculate the area of the sector.

Back

Area = (θ/360) * π * r², where θ is the angle in degrees and r is the radius.

Front

Simplify the expression: -3x²(7x² - x + 4)

Back

-21x⁴ + 3x³ - 12x²

Front

Find the Volume of the composite figure.

Back

Volume = V₁ + V₂ + ... + Vn, where V is the volume of each individual shape.

Front

Find the volume. Round to the nearest hundredth: Volume of a cylinder = πr²h

Back

Use the formula to calculate the volume and round to the nearest hundredth.

Front

Find the sum: (3y² + y³ - 5) + (4y² - 4y + 2y³ + 8)

Back

Combine like terms: 3y³ + 7y² - 4y + 3.

Front

Definition of a sector in a circle.

Back

A sector is a portion of a circle enclosed by two radii and the arc between them.

Front

Definition of composite figures.

Back

Composite figures are shapes that are made up of two or more simple geometric shapes.

Front

Formula for the area of a circle.

Back

Area = πr², where r is the radius of the circle.

Front

Definition of volume in geometry.

Back

Volume is the amount of space occupied by a three-dimensional object, measured in cubic units.

Front

How to simplify polynomial expressions.

Back

Combine like terms by adding or subtracting their coefficients.
