Question

The volume of a vessel in the form of a right circular cylinder is 448π cm³ and its height is 7 cm. Find the radius of the base.

Answer 1

Step-by-step explanation:

volume of vessel =448¶ cubic CM

=448x22/7

=1408cubic CM

height=7cm

πr2xh=1408cubic CM

22/7xr2x7=1408

22r2=1408

r2=1408/22

r2=64

r=√64

radius of base is 8cm

Answer 2

Answer:

GIVEN :-

❥ Height of a right circular cylinder = 7 cm

❥ Volume of a right circular cylinder = 448 cm³

Step-by-step explanation:

➵ πr²h = 448 × r² × h = 448

➵ 7r² = 448

➵ r² = $\frac{ 448 }{ 7 }$

➵ r² = 64

➵ r = √64

$\huge\green{ \: \: \: ➵ \: \: }$ r = 8

Therefore, the radius of its base is 8 cm.
