Answer: last option (5π√146 units²)
Step-by-step explanation:
To solve the exercise you must apply the formula for calculate the lateral area of a cone, which is shown below:
where r is the radius but L is the slant height.
As you can see in the figure attached:
But you need to find the slant height with the Pythagorean Theorem (L would be the hypotenuse):
Substitute into the formula, then:
units²
0.02/0.64*100=3.125℅
The formula is:(/error/divided by right answer) times 100. /means absolute value
The first one is correct but I don’t know about the second one
Answer:
800m
Step-by-step explanation:
The graph shown above is a "parabola" and the parent function is x². So, we can start off at x². The graph of x² intersects the x and y-axis at (0, 0). In this case, it's simply being shifted up by 1 and intersects the x and y-axis at (0, 1). Therefore, the equation is:
To check, let's plug in 0 for x, and see what we get (we should get 1):
We are right, so your final answer is
x² + 1.
