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 =
, 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.
Answer:
5x -8y
Step-by-step explanation:
3x+2x-8y
3x and 2x are like terms so we can combine them
5x -8y
Answer:
C° = 71.6056
Step-by-step explanation:
Law of Cosines: c² = a² + b² - 2abcosC°
Step 1: Plug in known variables
29² = 30² + 15² - 2(30)(15)cosC°
Step 2: Evaluate
841 = 900 + 225 - 900cosC°
-59 = 225 - 900cosC°
-284 = -900cosC°
71/225 = cosC°
cos⁻¹(71/225) = C°
C° = 71.6056
And we have our answer!
