Question

volume of sphere is 4
$4\pi \div 3volme of sphere find surfac area$


​

Answer 1

Step-by-step explanation:

Given--->

----------

Volume of sphere= (4π/3) cm³

To find---> Surface area of sphere

-----------

Solution--->

--------------

Volume of sphere=(4π/3) r³

=> 4π / 3 = (4π/3) r³

4π/3 cancel out from both sides

=> 1 = r³

Taking cube root of each side

=> (1)¹/³ =( r³) ¹/³

=> 1 = r

Now , surface area of sphere= 4πr²

=4 × 3.14 × (1)²

=4×3.14 ×1

= 12.56 cm²

Additional information---->

-------------------------------------

1)Volume of hemisphere=(2/3)πr³

2)Curved surface area of hemisphere

= 2πr²

3)Total surface area of sphere=3πr²
