## In the figure above A is the centre of the circle, A and D lie on BF and CE respectively, and B, D, F, and G lie on the circle. If BC=3, and DG bisects BF, what is the total area of the shaded regions?

Hi,

I am struggling with a question in the guesstimate section. Although you did a good job of clarifying I am still a bit confused as math isn’t my strongest suit. The question is:
p. 52, Q.20: In the figure above A is the centre of the circle, A and D lie on BF and CE respectively, and B, D, F, and G lie on the circle. If BC=3, and DG bisects BF, what is the total area of the shaded regions?

I am just wondering, how you would go about calculating the area of the shaded region in detail.

## How to approximate lengths with your thumb nail and a pencil

As anyone who’s ever chewed on a pencil knows, it doesn’t take much force to put a dent in a regular old #2 pencil. You might have an opportunity to use this to your advantage on the SAT. Occasionally, a geometry question will appear that asks you to figure out the length of a segment (more…)

## Figure drawn to scale? Guesstimate that ish.

Here’s an important thing to remember: all figures on the SAT are drawn to scale unless indicated otherwise. In other words, if it doesn’t say “Note: figure not drawn to scale,” underneath it, it is drawn to scale. Most figures on the SAT are drawn to scale, which means it’s a good idea to guesstimate whenever (more…)

## Have a go at this hard area question.

In the figure above, AB is the diameter of the circle, and AC = BC. What is the area of the shaded region?   (A) 4π – 2 (B) 2π – 1 (C) π (D) π – 1 (E) π – 2 Answer and explanation after the jump… As is usually the case with shaded region problems, the easiest way (and in this (more…)
