The lenth at the deep end is 12 ft becuase u divide 210 and 12 and if it goes into it evenly u got ur answer
Answer: Volume of the cylinder = 
Step-by-step explanation:
Volume of cylinder = Area of base x height
Also, area of cross section = Area of base
Volume of cylinder = area of cross section x height
Given: Area of cross section = 
height = 8 cm
Volume of cylinder = 614 x 8

Hence, the volume of the cylinder = 
Answer:
x = 4
Step-by-step explanation:
Using cosine triangle formula, we know that;
c² = a² + b² - 2ac(cos C)
From our diagram;
a = 2x
b = x + 1
c = 7
C = 60°
Thus;
7² = (2x)² + (x + 1)² - 2(2x)(x + 1)cos 60
49 = 4x² + (x² + 2x + 1) - (4x² + 4x)(0.5)
49 = 5x² + 2x + 1 - 2x² - 2x
3x² + 1 - 49 = 0
3x² - 48 = 0
3x² = 48
x² = 48/3
x² = 16
x = √16
x = 4
Answer:
15.
Step-by-step explanation:
3(x - 14) = 3
3x - 42 = 3
3x = 42 + 3 = 45
x = 15.
