Answer:
The volume of a cylinder = 78 \mathrm{cm}^{3}78cm3
Let us substitute the volume of cylinder in the formula.
The formula for volume of a cone is V=\frac{\pi r^{2} h}{3}V=3πr2h (1)
The formula for volume of a cylinder is V=\pi r^{2} hV=πr2h (2)
Substituting V=78V=78 in equation (2), we get,
\begin{gathered}\begin{array}{c}{V=\pi r^{2} h} \\{78=\pi r^{2} h}\end{array}\end{gathered}V=πr2h78=πr2h
Given that the cone has the same radius and height of that of the cylinder, let us substitute 78=\pi r^{2} h78=πr2h in equation (1)
\begin{gathered}\begin{array}{l}{V=\frac{\pi r^{2} h}{3}} \\{V=\frac{78}{3}} \\{V=26}\end{array}\end{gathered}V=3πr2hV=378V=26
Thus, the volume of a cone with the same radius and height of a cylinder is 26 \mathrm{cm}^{3}26cm3 .
It is true due to the commutative property of multiplication. If all of your operations are multiplication, then the integers can move around and you can still get the same answer.
^This is only true if you meant to type (1.8x3)x2.1=(1.8x2.1)x3
If you meant what you typed, then the equation is false. The left side would be 3 times the value of the right side due to the 3 being on the left side and not the right side while without the 3 the two sides would be equal.

Well it is obviously gonna be answer D because you have to find which one is closer to a whole number to find out the greatest Hope that Helped Bye ;)
Answer:
I can not give an exact answer seeing that I do not have access to that assignment but here is what I have. :)
Step-by-step explanation:
Seeing that the angle between "V" and "R" is a 90 degree angle, I can use that to determine the answer for the angle of F,P,V. It is too high for a 45 degree angle and too short for an 80. I then noticed that R,P,Q is about a 40 degree and since there is a 90 degree angle at V,P,R, I can use that and say F,P,V is about a 60-75 degree angle. Hope this helped! :D
