Hey there!!
Volume of a cone : πr²h/3
Where, πr²h is the volume of a cylinder.
Hence,
V cone = V cylinder / 3
Hence,
The above mentioned formula is wrong/false.
Hope my answer help!!
A
x=y^2-9
x+9=y^2
square root both sides
+-sqrt(x+9)
Answer:
An equation is a mathematical statement that shows the equal value of two expressions while an inequality is a mathematical statement that shows that an expression is lesser than or more than the other. 2. An equation shows the equality of two variables while an inequality shows the inequality of two variables.

Answer:
387 km
Step-by-step explanation:
The length of AC, b can be obtained using the cosine rule ; using the cosine relation:
b² = a² + c² - 2ac CosB
b² = 250² + 185² - 2(250*185) Cos125
b² = 62500 + 34225 - 92500 * −0.573576
b² = 96725 + 53055.820
b² = 149780.82
b = sqrt(149780.82)
b = 387.01527
b = 387 km (nearest whole number)
