Question

how to find volume and total surface arae of a cylinder whose radius and length are 7cm and 30cm

Answer 1

Answer:

Given :-

Radius of Cylinder = > 7 cm.

Height of Cylinder = > 30 cm.

Volume of Cylinder = > πr²h.

Total Surface area of Cylinder => 2πr(r+h)

Answer 2

Answer   Volume = $4620^{3}$    Total surface area = 1628cm

Step-by-step explanation:

Volume = $\pi *r^{2} *height$

1. 22/7 *7*7*30=$4620^{3}$
2. Total surface area =
3. $2\pi r(h+r)$
   $2*\frac{22}{7}*7*(30+7)$
4. $\frac{11396}{7}$
5. 1628
