Answer:

2120.58 centimeters³

Explanation:

First divide the diameter by 2 to get 9. The volume of a cone is 1/3*π*r²*h so  1/3*π*9²*25

This equals 2120.59 cm³ (cubed)

Answer:

I think the closest would be 41.5%

Step-by-step explanation:

If you take the number of passengers left on the plane and divide by the total number of passengers that were on the plane in the beginning, you would get 58.5%. That's the % of how many people are left on the plane. So, you would then do 100%-58.5% to get the answer 41.5%. Hope this helps! :)

Solve the equation log^7b>2
ahrayia [7]

Answer:

b > 12.71

Step-by-step explanation:

Here in this question we have to solve the inequality equation given for b (An unknown variable}

Now, the equation is (\log b)^{7} > 2

⇒ \log b > 2^{\frac{1}{7} }

We are taking the base of the log here is 10.

So, 10^{(\log b)} > 10^{2^{\frac{1}{7} } } {Since 10^{\log x} =x and e^{\ln x} = x}

⇒ b > 12.71 (Approximate) (Answer)
