Step-by-step explanation:
51 - 2j
maybe something is missing here, but that is the representation of what you wrote.
It’s equals 176 square cm
(8.4*10^8) + (4.2*10^7)
= 882,000,000
= 8.82*10^8
Hope it helped :)
The answer is: 
The explanation is shown below:
1. To solve this problem you must apply the following proccedure:
2. You have the logarithm expression:

3. First, you must apply the following property:

4. Therefore, you have:

5. By applying logarithm on both sides, you have:

6. By applying the property
:

7. Solve for x:

Answer:
<u>The volume of this figure is approximately 418.88 centimeters squared!</u>
Step-by-step explanation:
The volume for a right circular cone is V = (π)(r^2)(h/3)
Substituting known values is as follows:
V = (π)(r^2)(h/3)
V = (π)(4^2)(25/3)
V = (π)(16)(25/3)
<u>V ≈ 418.88 cm^3</u>
