first, divide the pentagon into 5 isosceles triangles. the length of the two equal sides of each triangle is equal to the radius of the circle.

second, compute the total angle which is 360 degrees by the number of sides of the polygon..i.e. 360/5 = 72 degrees.

third, compute the area of one triangle using the formula involving two sides and an included angle. i.e. A = 1/2(9)(9)sin(72deg)

then, Area of pentagon is equal to area of one triangle multiplied by the number of sides of the polygon.

Expertise

I can help people "translate" a word problem into an algebra equation. (With very basic questions, I can show people how to think through the problem and solve it without using algebra.) In most cases, I can then show a step-by-step solution of the equation. I do not do trig or calculus and I do not solve problems involving exponents.

Experience

I have tutored basic math and algebra for over 30 years. I have taught classes to prepare students to take the PSAT, SAT, GRE and GMAT college admission tests, all of which feature word problems. I have a lot of experience with solving multiple these exam problems without using algebra at all.
