Answer 2

Answer:

The volume of the cylinder is 507.084cm³

Step-by-step explanation:

Given: h = 7cm ; C.S.A. = 211.2cm² ; Volume,V=?

w.k.t., C.S.A. = 2πrh

⇒ 2πrh = 211.2

⇒ r = 211.2/2πh

⇒ r = 105.6/πh

Also, Volume, V = πr²h

⇒ V = πh×$(\frac{105.6}{h\pi})^{2}$

⇒ V = $\frac{105.6*105.6}{h\pi}$

⇒ V = $\frac{11151.36}{7*3.14}$

⇒ V = 507.084cm³
