(a)
To Compare: The area of two sectors.
(a)
Answer to Problem 7CE
Area of sector of bigger
Explanation of Solution
Given: If they have same central
Let the radius of smaller be
Then
Radius of bigger circle be
Thus
Using area of sector formula.
On comparing
We get to know that
Area of sector of bigger circle is four times as much as the smaller circle.
(b)
To Compare: The area of two sectors.
(b)
Answer to Problem 7CE
Area of sector of bigger central angle is twice the area of sector of smaller sector.
Explanation of Solution
Given: If they have same radius but central angle of one is twice as long as central angle of other.
Let the angle of smaller be
Then
Central angle of bigger circle be
Thus
Using area of sector formula.
On comparing
We get to know that
Area of sector of bigger central angle is twice the area of sector of smaller sector.
