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

Back

The surface area of a cylinder is given by the formula: SA = 2πr(h + r), where r is the radius and h is the height.

How do you calculate the cost of materials based on area?

Back

To calculate the cost of materials based on area, multiply the area (in square feet) by the cost per square foot.

What is the significance of the SSA condition in triangle congruence?

Back

The SSA (Side-Side-Angle) condition does not guarantee triangle congruence, as it can lead to ambiguous cases.

What is the relationship between the lengths of the sides of a right triangle?

Back

In a right triangle, the lengths of the sides are related by the Pythagorean theorem: a² + b² = c², where c is the hypotenuse.

What is a special right triangle?

Back

A special right triangle is a triangle with angles of 30-60-90 or 45-45-90 degrees, which have specific ratios for their sides.

How do you find the length of the hypotenuse in a 30-60-90 triangle?

Back

In a 30-60-90 triangle, the lengths of the sides are in the ratio 1:√3:2. The hypotenuse is twice the length of the shorter leg.

What is the formula for the distance in a right triangle when given the lengths of the other two sides?

Back

The distance can be found using the Pythagorean theorem: c = √(a² + b²), where c is the hypotenuse.
