Question

find the volume of sphere whose radius is 4.5​

Answer 1

Answer:

❥ANSWER

Volume of sphere=4/3πr³

Given radius=4.5

Volume=4/3×22/7×4.5×4.5×4.5

=>4/3×22/7×91.12

=>8018.56/21.

=>381.83cm³

❥Volume of given sphere is 381.83cm³

Answer 2

$\huge\rm\underline\purple{Question :-}$

Find the volume of a sphere whose radius is 0.63m

$\huge\rm\underline\purple{Answer :-}$

$\boxed{ \sf \green{ Given, }}$

• Radius of the sphere, r = 0.63cm

$\boxed{ \sf \red{ To\: find, }}$

• Volume of the sphere = ❓

$\green{\underline\bold{We\:know\:that,}}$

$\boxed{ \sf \blue{ Volume\: of\: a\: sphere=\: \frac{4}{3}Πr3}}$

= $\frac{4}{3}$× $\frac{22}{7}$× 4.5 × 4.5 × 4.5

= $\frac{4}{3}$× $\frac{22}{7}$× $\frac{45 }{10}$ × $\frac{45 }{10}$× $\frac{45 }{10}$

= 381.85 cm3

$\pink{\underline\bold{ ∴ \:The\:required\:answer\:is\:381.85\: cm3}}$
