Area of a circle is found using the formula: A = PI x r^2 where r is the radius of the circle, which is half the diameter.
Using the information in the problem you have:
A= PI x 15^2
A = PI x 225
A = 706.5 sq. In.

Step-by-step explanation:
Man this one is a world of its own :D Just a quick question are you a fellow Add Math student in O levels i remember this question from back in the day :D Anyhow Lets get started
For this question we need to know the following identities:

Lets solve the bottom most part first:

Take LCM

now break the LCM

because 1/tan = cot x
and furthermore,

now we solve the above part and replace the bottom most part that we solved with 

Hence proved! :D
