Calculate the volume of a cylinder, radius 12.5 cm and height 14 cm

Morgarella [4.7K]

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=12.5\\
h=14
\end{cases}\implies V=\pi \cdot 12.5^2\cdot 14$

Ab - bc+ ac, bc - ca+ ab, ca - ab-2bc

BabaBlast [244]

Answer:

$ab-2bc+ca$

Step-by-step explanation:

Complete question is given below

Add:-

ab-bc+ac,bc-ca+ab,ca-ab-2bc

We have to find the result after addition

Now, adding all expression

We get

$ab-bc+ac+bc-ca+ab+ca-ab-2bc$

Combine like terms then, we get

$(ab+ab-ab)+(bc-bc-2bc)+(ac-ca+ca)$

$ab-2bc+ca$

Hence, $ab-bc+ac+bc-ca+ab+ca-ab-2bc=ab-2bc+ca$
