Question

Calculate the radius and surface are of a sphere of voloum 850m square.​

Answer 1

Answer:

Hii,

Step-by-step explanation:

$\huge\boxed{\boxed{\mathcal\red{Answer:-}}}$

$\sf\bold{Given:-}$

$\bold\rightarrow$ Volume of the sphere = 850m²

$\sf\bold{To \: Find:-}$

$\bold\rightarrow$ Radius and Surface area of the sphere

$\huge\bold{\underline{Solution:-}}$

$\rightarrow$ Volume of the sphere = 4/3 πr³

$\rightarrow$ 850 = 4/3 × 22/7 × r³

By solving this, we find that the radius of the sphere is 5.88 m

$\therefore$ The radius of the sphere is 5.88 m

$\sf\bold{\underline{Now,}}$

$\rightarrow$ The surface area of the sphere = 4πr²

$\rightarrow$ Surface area of the sphere = 4 × 22/7 × (5.88)²

$\rightarrow$ Surface area of the sphere = 4 × 22/7 × 34.57

$\rightarrow$ Surface area of the sphere = 21,295.12 m²

$\therefore$ The surface area of the sphere is 21295.12 m²

$\sf\bold{\underline{Hence,}}$

The radius of the sphere is 5.88 m

And, The surface area of the sphere is 21295.12 m²
