Given:
The shaded sector above covers of the circle.
Radius of the circle = 3 cm
To find:
The area of the sector in terms of π.
Solution:
The area of a circle is
Substituting , we get
It is given that the shaded sector above covers of the circle.
The area of shaded sector
Therefore, the area of shaded sector is 3π sq. cm.
The point-slope form:
We have the points (3, -4) and (5, 1). Substitute:
The standard form:
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>
