A pyramid has a square base and a height of 6 ft. The volume of the pyramid is 162 ft^3. Let s be the length of a side of the py
geniusboy [140]

Answer:

(a)s^2\\(b)162=2s^2\\(c)s=9$ ft

Step-by-step explanation:

(a)Base Area

Side length of square base=s

Area of a Square of side length s=s^2$ ft^2

(b)

  • Height =6 ft
  • Volume=162 $ ft^3.

Volume of a Pyramid=\frac{1}{3}X$Base Area X Height

Substituting the given values, we have:

162=\frac{1}{3}Xs^2 X 6\\\\162=2s^2

(c)Solving the equation derived from (b)

162=2s^2\\$Divide both sides by 2\\s^2=81\\s^2=9^2\\s=9$ ft

Solving this equation shows that s =9 ft.

Which is greater 0.086 or 86%
cupoosta [38]
Hey there! 

In order to find out which one is greater, lets convert both of them into percents. 

To convert a decimal into a percent, simply multiply the decimal by 100 or move the decimal two places to the right. 

So! 
0.086 × 100 = 8.6%

Now, we know that 0.086 is equal to 8.6% So, the correct answer is 86% 

86% is greater than 0.086.
