Answer:
see the procedure
Step-by-step explanation:
we have
where
c -----> the cost in dollars
g ----> the number gallons of gas purchased
1) For g=1 gal
substitute the value of g in the equation and solve for c
The pair (1,2.95) fit the relationship
2) For g=3 gal
substitute the value of g in the equation and solve for c
The pair (3,8.85) fit the relationship
3) For g=5 gal
substitute the value of g in the equation and solve for c
The pair (5,14.75) fit the relationship
4) For c=$20.65
substitute the value of c in the equation and solve for g
The pair (7,20.65) fit the relationship
Answer:
1 ) 49,062.5 feet square
2) 64 π inch square .
3) 9 π meter square .
4) 289 π ft square.
5) 225 π cm square .
Step-by-step explanation:
1) From the above figure we can see that diameter of pond is given as 250 ft.
So we easily calculate the area of circular pond by using the area formula of circle.
AREA
= 0.785 × 250 × 250 ft square
= 49,062.5 ft square .
2) In the second figure diameter is given as 16 inches .
AREA
=
= 64 π inch square .
3) Here the diameter is given as 6 m .
AREA
= 9 π meter square .
4) Here the radius is 17 ft .
AREA = π × radius ×radius
= π × 17 × 17 ft. square .
= 289 π ft square.
5) Here the radius is give as 15 cm.
AREA = π × radius ×radius .
= π × 15 × 15 cm square .
= 225 π cm square .
