Answer:
Radius = 5
center is (19,-1)
Step-by-step explanation:
Two points in the plane, (19,4) and (19,−6), represent the endpoints of the diameter of a circle.
Distance between the points is calculated using formula
diameter = 10
radius = diameter divide by 2
Radius = 5
midpoint is the center of the circle
(19,-1)
Equation of the circle
h,k is the center and r is the radius
h=19 and k=-1 , r=5
Answer:
The value of x is 8 gallon.
Step-by-step explanation:
Given a table showing approximate conversion from gallons to liters.
Number of Gallons 2 4 x
Number of Liters 7.6 15.2 30.4
We are required to find value of x,
Given : 2 gallon is equal to 7.6 liters.
⇒ 1 liter is equal to liters. ........(1)
given, x gallon equal to 30.4 liters.
⇒ 1 liter is equal to liters. .........(2)
from (1) and (2),
⇒
Solving for x, we get,
⇒
⇒
Approximately x = 8
Thus, the value of x is 8 gallon.
