Answer:
The area of each section of the circle is 
Step-by-step explanation:
we know that
The area of a circle is equal to

we have

substitute

To find the area of each section divide the complete area of the circle by 
so

To get this you substitute 7 for the x.
7/8(7)-1/2
49/8-1/2
49/8-4/8
45/8 is the value.
Answer:
a-b = 5x² + 6x -8
Step-by-step explanation:
a = 3x² + 5 -6 ⇒ 3x² -1
b = -2x² -6x + 7
a-b
3x² -1 -( -2x² - 6x + 7)
3x² -1 + 2x² + 6x -7
5x² + 6x -8
Answer:
b) √29
Step-by-step explanation:
Given: The origin is (0, 0), the point P is (2, -5).
We need to use the distance formula.
Distance formula = 
Here x2 = 2, x 1 = 0, y1 =0, y2 = -5
Distance = 
= 
= √(4 + 25)
= √29
The answer is b) √29
Hope you will understand the concept.
Thank you.
