I need help with this
balandron [24]

Answer:

27

Step-by-step explanation:

Area of Triangle x 2 = 3 * 3

The reason I did not divide it by 2 is because of how the other triangle is bound to have the same area. Just leave it as it is because later you're going to reach the same answer.

3 * 3 = 9

Rectangle Area = 6 * 3 = 18

18 + 9 = 27

True or false: the lateral surface of cone a is exactly 1/2 the lateral surface area of cylinder b
Mazyrski [523]

Answer:

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 = \pi r\times l, where l is the length of the lateral side.

So, we get L_{A} = \pi r\times h.

Also, Lateral surface area of cylinder is 2\pi r\times h, where h is the height of the cylinder.

So, we get L_{B} = 2\pi r\times h

Thus, we see that, L_{A}=\frac{1}{2}\times L_{B}

Hence, the given statement is correct.
