Question

calculate the volume of a sphere having surface area equal to 154 sq. cm cube
​

Answer 1

Answer:

Step-by-step explanation:

Surface Area =154 square cm.

 $4\pi r^{2}$=154

r²=  154/4×7/22 =  4 /49

​ r= 7/2  cm

Volume,

V= 4/3$\pi r^{3}$  

​ V=4/3 X 22/7 X ($(\frac{7)}{2^} )^{3}$

​ V=179.66 cm³

Answer 2

Answer:

4πr² = 154

πr² = 38.5

r² = 12.25

r = √12.25 = 3.5cm

volume of sphere = 4πr³ /3

= 4*3.14*3.5*3.5*3.5/3

= 539/3

= 179.667cm³
