Explanation

The area of the sector can be calculated using the formula: Area = (θ/360) * πr², where θ is the central angle and r is the radius.

Given θ = 60° and r = 5 cm, we can substitute these values into the formula:

Area = (60/360) * π * (5)²

Area = (1/6) * π * 25

Area ≈ (1/6) * 3.14 * 25

Area ≈ 13.08 cm²

Explanation

Let's simplify the expression:

√1-sin²θ/sinθ = √(cos²θ)/sinθ (since 1 - sin²θ = cos²θ)

= cosθ/sinθ

= cotθ

Explanation

An angle less than 90° is called an acute angle.

Exactly 90°: Right angle

Between 90° and 180°: Obtuse angle

Exactly 180°: Straight angle

More than 180° and less than 360°: Reflex angle

Explanation

The formula for area is:

Area = Length * Width

96 = L * 3

L = 96 / 3

L = 32
