Answer:
radius = 5 in
Step-by-step explanation:
Using the formula for calculating the area (A) of a circle
A = πr² ( r is the radius )
here A = 78.5, hence
3.14r² = 78.5 ( divide both sides by 3.14 )
r² = = 25 ( take the square root of both sides )
r = = 5
Answer:
Step-by-step explanation:
The vertices of quadrilateral ABCD are A(1,0) B(5,0) C (7,2) D(3,2).
The slope of side AB is
The slope of side BC is
The slope of side CD is
The slope of AD is
We see that the opposite sides of the quadrilateral ABCD are equal.
Hence the quadrilateral is a parallelogram
