Answer:
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The distance between the center and any point that lie on the circle is equal to the radius
we have the points
(5,-4) and (-3,2)
the formula to calculate the distance between two points is equal to
substitute the values
step 2
Find the equation of the circle
we know that
The equation of a circle in standard form is equal to
where
(h,k) is the center
r is the radius
we have
substitute
Answer:
D-- if a is a number between 0 and 1, the quotient will be greater
Step-by-step explanation:
Answer:
861.56 km2
Step-by-step explanation:
the formula for the area of a trapazoid is
a= (a+b/2) + h
100-30=70-50=20
there's your equation
283 divided by 12.3 = 23.008 and rounded it will just be 23.
