What is the area the major sector aob?

11.59 units²

Step-by-step explanation:

Step 1 : Determine radius

From reading the graph, looks like the radius is approx 3.2 units

Alternatively,  calculate the radius:

the height of the triangle AOB = 1 unit, 1/2 base of triangle AOB = 3 units.

Using Pythagorean theorem, hypotenuse OB of a right angle triangle,

= √(1² + 3²) = √10 = 3.16 (pretty close to our estimate above)

Area of major sector,

= * area of full circle

= * 2πr

= * 2π (3.16)

= 11.59 units²

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
