BTW if it's EASY then try but anyway,there you go!!
B or D, I forgot whether the open circle or the circle is the equal to one, if I had to guess I'd say B
P = paddling speed
C = speed of the current
Upstream: 6 = 4 (P - C. Downstream: 6 = 3 (P + C)
4P - 4C = 6
3P + 3C = 6
12P - 12C = 18
12P + 12C = 24
Add the equations:
24P = 42. P = 42/24 = 1.75 mph
Subtract the equations:
-24C = -6
C = 0.25 mph
35 because you can not multiply both numbers by the same number to get a smaller Greatest common multiple
The area of the circular fire pit is 4096 square inches.
Explanation:
Given that the rectangular fire pit is 7 feet by 6 feet.
We need to determine the area of the largest circular fire that can be made in this fire pit.
The diameter of the circular fire is 6 feet
The radius is given by

Radius is 3 feet.
The area of the largest circular fire pit can be determined using the formula,

Substituting the values in the formula, we have,



We need to convert feet to inches by multiplying by 12, we get,


Rounding off to the nearest square inch, we get,

Thus, the area of the circular fire pit is 4096 square inches.
