Question

49. The volume of a sphere is 26,244 at cm. What is its surface area?
a. 1070 T cm b. 1402 r сm c. 2448 t cm² d. 2916 t cm​

Answer 1

Answer:

Given :-

Volume = 26,244 cm²

To Find :-

Surface Area

Solution :-

26244 = 4/3π³

26244 = 4/3 × 22/7 × r³

26244 = 88/21 × r³

26244 × 21/88 = r³

6262 ≈ r³

18.5 = r

Now

Surface Area = 4πr²

Surface Area = 4 × 22/7 × (18.5)²

Surface Area = 4 × 22/7 × 342.25

Surface Area = 88/7 × 342.25

Surface Area = 4302 cm²
