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
Answer:
I believe the answer is C.
Step-by-step explanation:
I put in 9 into the y
6(9)= 54
4(9)+18=
36+18= 54
Add them with the right angles (which are 90)
Leaves the other angles KLH, FLH being 36
Answer: explain the meaning of
Step-by-step explanation:
Answer:
im pretty sure its -9
Step-by-step explanation:
the equation explained would look something like this...
-5x-22=23
so you would isolate the variable by first adding 22 to both sides and the dividing by -5 on both sides
-5x-22=23
+22 +22
-5x/-5=45/-5
x=-9
