True or false: the lateral surface of cone a is exactly 1/2 the lateral surface area of cylinder b

True

Step-by-step explanation:

We have that,

The cone A has the length of the lateral side = h and the height of the cylinder  B = h.

Since, the lateral surface areas are given by,

Lateral surface area of cone = , where l is the length of the lateral side.

So, we get = .

Also, Lateral surface area of cylinder is , where h is the height of the cylinder.

So, we get =

Thus, we see that,

Hence, the given statement is correct.

callens expression makes sense because they are showing that the five is negative and it is also being multiplied to the set of parenthesis.

demetrius's expression is a simplified version of callens. Using the parenthesis around the -5 shows that not only is that number negative, but it will also be multiplied to the -4 in the parenthesis.
