Which measurement is closest to the circumference of a circle with an area of 36 square feet?
A
12.0 feet
B
21.3 feet
С
103.2 feet
D
113.0 feet
The measurement of the circumference of a circle is 21.3 ft.
What is Circumference of Circle?The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.
Here, given area of circle = 36 ft²
Area of Circle = πr²
36 = 3.14 X r²
r² = 11.46
r = 3.38 ft.
Circumference of Circle = 2πr
= 2 X 3.14 X 3.38
= 21.25 ft. ≈ 21.3 feet
Thus, the measurement of the circumference of a circle is 21.3 ft.

Maia says that the lines in this system of linear eqations are parallel. is she correct? explain.
2x+y=14
2y+4x=14
Answer:
yes, they are parallel because their slopes are the same
Step-by-step explanation:
if you put each equation into slope-intercept form and compare slopes you can see whether they are parallel or not
2x + y = 14
y = -2x + 14
slope = -2
2y + 4x = 14
2y = -4x + 14
slope = -4/2, which simplifies to be -2

Work out the difference, in minutes, between 1 hour 50 minutes and 1 3/4 hours
Answer:
Step-by-step explanation:
1 hour nd 50 = 60 min +50 min= 110 minutes
1 hour and 3/4= 60/4= 15 x 3= 45
1 hour and 3/4= 60 min + 45 min= 105 minutes
110- 105= 5 minutes difference
5 minutes
1/4 of an hour is 15 minutes so times that by three you get 45 minutes. 50 minutes - 45 minutes = 5 minutes,
