Math 3 - EOC Review Flashcard #1

Front

What is the formula for the volume of a cone?

Back

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

Front

How do you find the radius of a circle from its equation?

Back

Rewrite the equation in the form (x-h)² + (y-k)² = r² to identify the radius r.

Front

What is the coordinate on the unit circle at 0°?

Back

(1, 0)

Front

What is the coordinate on the unit circle at 90°?

Back

(0, 1)

Front

What is the coordinate on the unit circle at 180°?

Back

(-1, 0)

Front

What is the coordinate on the unit circle at 270°?

Back

Front

How do you convert degrees to radians?

Back

Multiply degrees by π/180.

Front

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

Back

Radius = Diameter / 2.

Front

What is the area of a circle?

Back

Area = πr², where r is the radius.

Front

What is the circumference of a circle?

Back

Circumference = 2πr, where r is the radius.
