... the area of a circle. You will also learn how to find the area of a sector , which is a slice of a circle, similar to ...slice of pie or pizza. Circumference Formula Find great deals and save! ...

There are two common (but not the only) methods to solve this. First method: (By formula ) Note that the formula for the area of a sector is 1/2 * r^2 * theta, where r is the radius of the circle (which ...

Area of triangle = (b * h) /2 where b - base of the triangle and h - height of the triangle Area of a sector = pi * r^2 * theta / 360 where pi = 3.14 r - radius of the sector theta - angle of the sector

... at the center between the two radius points at the ends of the arc . θ must be in radians] area of a sector = (1/2)θr²,[ this is the area between the arc, and the two radius ...

You need to use 2π in place of 360 because the 360 is degrees but the angle 3π/2 is in radians. Or, you can change 3π/2 to degrees (270 º) 270/360 • π (4²) 3/4 π • 16 12π

... more than one way to find arc length and sector area . It depends on..., Height of segment, Central ...two of these, you can calculate the rest. ::::: A sector is a wedge of the ...

The formula for arc length is a fraction of the whole circumference based on the central angle. The formula for sector area is a fraction of the whole area of a circle based on the central angle.

Sectors are a bit like triangles with altitude r and base rθ, the arc length of the sector . So the area is (1/b)(base)(altitude... designed to make all these formulas simple.
