Geometry Unit 4 Review

Front

What is the formula for finding the arc length of a circle?

Back

Arc Length = (θ/360) * 2πr, where θ is the central angle in degrees and r is the radius.

Front

What shape is formed by the horizontal cross section of a cylinder?

Back

Circle.

Front

How do you calculate the volume of a cone?

Back

Volume = (1/3)πr²h, where r is the radius and h is the height.

Front

What is the volume of a sphere?

Back

Volume = (4/3)πr³, where r is the radius.

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

What is a tangent line in relation to a circle?

Back

A tangent line is a straight line that touches the circle at exactly one point.

Front

How do you find the volume of a composite shape?

Back

Calculate the volume of each individual shape and then sum them up.

Front

What is the relationship between the radius and diameter of a circle?

Back

Diameter = 2 * Radius.

Front

What is the formula for the surface area of a cylinder?

Back

Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is the formula for the surface area of a cone?

Back

Surface Area = πr(r + l), where r is the radius and l is the slant height.
