Answer:
The radius is 12.
Step-by-step explanation:
You're given the center and a point on the circle. The point and the center both have an x-coordinate of -5, so there is no horizontal distance between them. The distance is only in the vertical direction. The distance from 8 to -4 is 12. Since this is the distance from the center to a point on the circle, this equals the radius.
First, you have to substitute for x, which would make the problem f(x)=7.45(-4.3)+33.7
Now, you just have to use the PEMDAS method (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
f(x)= -32.035+33.7
f(x)=1.665
4• y because since the brackets are multiplying the dot represents the x
Answer:
Step-by-step explanation:
Given:
Length of radius of circle = 5 feets
Length of perpendicular bisector = 4 feets
To find:
Area of the shaded portion of the circle
Solution:
As OD is perpendicular bisector of AB,
Area of 
= 1/2 (base) × (height) = 
square feets
Area of sector AOBC = 
square feets
Here, r denotes radius of circle
So,
Area of shaded portion = Area of sector AOBC - Area of =
