Answer:
The volume of the figure is
Step-by-step explanation:
we know that
The volume of a triangular pyramid is equal to
where
B is the area of the base
H is the height of the pyramid
Find the area of the triangular base B
we have
substitute the values
Step-by-step explanation:
I think 160! I don't know it true or not
Answer: a. 14% decrease or 86% of the whole
B. 137.5% increase
Step-by-step explanation:
A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%
B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5
It's the formula for the volume of a cylinder with radius r and height h.
The greatest value that the remainder may have when divided by 16 is 15.
Thus, your required answer is 15.
