Answer:
The volume of the cone is approximately 453.0 cm³
Step-by-step explanation:
The volume of a cone is one third that of a cylinder with the same height and radius. That gives us 1/3 πr²h, where r is radius and h is height.
However, we are not given the height of the cone, but the side length. We can work out the height using the Pythagorean theorem, as we have a right triangle with the height, base radius, and length. You may recall that the Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of it's other two sides:

So we can find the height of the cone with that:

Now that we have the cone's height, we can solve for its volume:

Answer:
it's 80.
Step-by-step explanation:
120-40= 80
....
X+y=3
Subtract x from both sides
y=-x+3
Substitute
2x--x+3=6
2x+x+3=6
3x+3=6
Subtract 3 from both sides
3x=3
Divide both sides by 3
x=1
The correct answer is 900yds.
Answer: 1
Step-by-step explanation:
Alright, lets get started.
The given expression is :

As per Pythagorean identity,

taking 1 to left side and
to right side

Now plugging the value of
in given expression

cosx will be cancelled, so

Multiplying -1 in both sides, it will equal to
........................ Answer (C)
