Keisha has a straightedge and a compass, but noprotractor. What kind of angle can Keisha draw exactly with only these tools?

Straight (it's a straight line!), full rotation (a circle), but nothing else since you can't measure the exact angle of it

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.

Yes, since the other two numbers on each side are the same, any number can fit well in this equation.

36. U get 36 because 36 divided by 4 equals 9 and 36 and 4 can’t go any further than that.
