Questions and Answers

What is the formula for finding the circumference of a circle?

2π/r

π/2r

2πr (correct)

πr^2

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

Diameter = 2 * Radius (correct)

Diameter = π * Radius

Diameter = Radius/2

Diameter = Radius^2

Study Notes

Circle Properties

The formula for finding the circumference of a circle is not specified, but it is typically C = 2πr or C = πd, where C is the circumference, r is the radius, and d is the diameter.
The diameter of a circle is equal to twice the radius (d = 2r).
The area of a circle with radius 'r' is A = πr^2.

Triangle Properties

In a right-angled triangle, the side opposite the right angle is called the hypotenuse.
The sum of the interior angles of a triangle is 180 degrees.
The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides in a right-angled triangle (a^2 + b^2 = c^2, where a and b are the other two sides, and c is the hypotenuse).
