Answer:
A) 60π cm³
Step-by-step explanation:
Given:
The<u> radius </u>of the base of a metallic rod is<u> 2 centimetres</u>, and its<u> height is 15 centimetres.</u>
Question asked:
What is the<u> volume </u>of this cylinder?
<u>Solution</u>:
As we know''
![Volume\ of\ cylinder=\pi r^{2} h](https://tex.z-dn.net/?f=Volume%5C%20of%5C%20cylinder%3D%5Cpi%20r%5E%7B2%7D%20h)
![=\pi \times2\times2\times15\\ \\ =60\pi](https://tex.z-dn.net/?f=%3D%5Cpi%20%5Ctimes2%5Ctimes2%5Ctimes15%5C%5C%20%5C%5C%20%3D60%5Cpi)
Therefore, the volume of this cylinder will be ![60\pi\ cm^{3}](https://tex.z-dn.net/?f=60%5Cpi%5C%20cm%5E%7B3%7D)

Answer:
(g+5)x(g-3)
Step-by-step explanation:
Edmentum/PLATO answer:
Rewrite the expression:
g+1/g^2+5g-3g-15 + g+3/g+5
Factor out g from expression:
g+1/gx(g+5)-3g-15 + g+3/g+5
Factor out g+5:
g+1/(g+5)x(g-3) + g+3/g+5
Least common denominator: (g+5)x(g-3)
Answer:
225πcm²
Step-by-step explanation:
The formula for the area of a circle is:
![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%20)
So you need to substitute values in.
![\pi{15}^{2} = \pi225 \: = \: 225\pi](https://tex.z-dn.net/?f=%20%5Cpi%7B15%7D%5E%7B2%7D%20%20%3D%20%5Cpi225%20%5C%3A%20%20%3D%20%20%5C%3A%20225%5Cpi)
