Answer:
The area of the circle is 
Step-by-step explanation:
step 1
Find the diameter of circle
we know that
The diameter of the circle is equal to the distance AB
the formula to calculate the distance between two points is equal to
substitute the values
therefore
the diameter of the circle is
step 2
Find the area of the circle
The area of the circle is equal to

----> the radius is half the diameter
substitute


C. 55 gallons because the formula for cylinder volume is V=pi•radius^2•height. So plug in the given values like in the pic below and then divide that by 231 to find the gallons
Answer:
20 X 40 = 800 (split into 2 fourths) = 40
Step-by-step explanation
20 x 40 = 800;
For 2 necklaces she can split 800 into fourths.
800 - 40 = 80. (1 fourth)
80 - 40 = 40 (2 fourths)
40 - 40 = 0 (3 fourths)
She could split 800 into 2 fourths to get a number more than 0 and less then 42.
The best estimate of rounding 42 is 40. Because 40 is closer to 42.

Answer:
25/24
Step-by-step explanation:
sin x = O/H = -7/25
cot x = A/O = -24/7
sec x = H/A
if sin x = -7/25, the opposite side is 7, and the hypotenuse is 25
if cot x = -24/y, the adjacent side is 24 (and the opposite side is still 7)
since H = 25 and A = 24, sec x = 25/24
Also, you know it's positive because when sin x is negative, the angle is in quadrants 3 or 4, and when cot x is negative, the angle is in quandrants 2 or 4, so the only quadrant that satisfies both is 4. In quadrant 4, sec x is positive.
