# Finding the Area of a Polar Region In Exercises 7-18, Find the area of the region. Interior of  r = 6 sin θ

To determine

To calculate: The value of area of interior region of polar equation r=6sinθ.

Explanation

Given:

The polar equation is r=6sinÎ¸.

Calculation:

Use the following steps in Ti-83 calculator to plot the graph:

Step1: Press [MODE] Key and select POL mode.

Step2: Press (Y=) Key.

Step3: Press r1=6sinÎ¸

Step4: Now press the [GRAPH] key and the graph of the equation is obtained:

Shaded section bounded by the curve r=6sinÎ¸ is given away below:

From the figure, it can be seen that Î¸ varies from 0 to Ï€

Therefore, the area of shaded region bounded by graph of r=f(Î¸) between the radial lines Î¸=Î± and Î¸=Î² is:
