Answer:
13.994
Step-by-step explanation:
We know that the base of the cylinder is a circular base.
So circumference of base = 
Given 
Volume of a cylinder = 
= 539
Substitute r into the formula for volume of cylinder.
Now, we will cancel 
from the numerator and denominator.
Answer:
Independent: miles travelled
Dependent: gallons of gas
Gas remaining after 68 miles: 7.2 gallons
Step-by-step explanation:
Looking at the table, it appears that after every 17 miles of driving, 1 gallon of gas is used.
- 68 miles would be the next 17 miles after driving 51 miles
- this means another gallon of gas would be used, so 8.2 - 1 = 7.2 gallons left
The <u>dependent variable</u> is the variable that depends on that of another
- In this case, the dependent variable is the gallons of gas, because in order for the car to drive, it needs gas
The <u>independent variable</u> is the variable that does not depend on that of another
- In this case, the independent variable is the miles travelled
Answer:
Step-by-step explanation:
General form of circle: (x - h)² + (y- k)² = r²
r - > radius and h ,k are the coordinates of the center.
5) (x - 5)² + (y- 1)² = 64 = 8²
radius: 8 ; Center (5 , 1)
6) (x + 7)² + (y- 2k)² = 324 = 18²
Center = ( -7 , 2) ; radius = 18 ; diameter = 18 *2 = 36
7) (x )² + (y + 10)² = 42.25 = 6.5²
Center = (0 , - 10); radius = 6.5 ; diameter = 6.5*2 = 13
8) (x - 6)² + (y + 1)² = 80 = (4√5)²
Center =(6, -1) ; radius = 4√5
Isn't the "Property of Subtraction,"?
