Answer:
B
Step-by-step explanation:
The volume of a cone (V) is calculated as
V = 
πr²h ( r is the radius and h the height )
Here V = 151 and r = diameter ÷ 2 = 12 ÷ 2 = 6 , then
πr²h = 151 ( multiply both sides by 3 to clear the fraction )
πr²h = 453 , that is
3.14 × 6² × h = 453
3.14 × 36h = 453
113.04h = 453 ( divide both sides by 113.04 )
h ≈ 4 m ( to the nearest metre ) → B

Answer:
(x+8)^2 - 60 = 0
Step-by-step explanation:
x^2 + 16x + 4 = 0
x^2 + 16x + 64 - 60 = 0
(x + 8)^2 - 60 = 0
-2(9 - x - 7)
= -2(2 - x)
= -4 + 2x
Answer:
-4 + 2x

Answer:
x = 6
Step-by-step explanation:
x = 3 sin(90) / sin (30)
x = 3(1)/(1/2)
x = 3 ÷ 
x = 6
