Calculate surface area of sphere whose volume is 4851cm3

Answer 1

Hey

Here is your answer,

Your question : Calculate surface area of sphere whose volume is 4851cm3

Solution :

Given,

Volume of the sphere = 4851 cm³

Now, we know that,

Volume of sphere = (4/3)πr³

4851 cm³ = (4/3)πr³

r³ = 4851×(3/4)×(7/22)
r = 10.5

Now we know that,

Surface area of sphere = 4πr²

= 4× (22/7)× 10.5²

= 1385.44 cm²

Hope it helps you!

Answer 2

Hey mate!

Here's your answer!!
________________

Volume of the sphere = 4/3πr³
Given volume = 4851cm³

$\frac{4}{3} \pi \: r {}^{3} = 4851$

$r {}^{3} = 4851 \times \frac{3}{4} \times \frac{1}{\pi}$

$r {}^{3} = 1157.625$

$r = 10.5$
Surface area of the sphere = 4πr²

$= 4 \times \frac{22}{7} \times 10.5 \times 10.5$

$= 1386 \: sq.cm$
