Question

if total surface area

area of a sphere is 154m sqare find it's total volume

​

Answer 1

Answer:

a=154m^2

Step-by-step explanation:

A=4πr^2

154=4πr^2

154/(4*3.14)=r^2

38.5/3.14=r^2

12.26=r^2

3.5m=r

Volume

V=4 /3πr^3

 =179.6m^3

Answer 2

Answer:

Volume = 179.66m³

Step-by-step explanation:

Here, 4πr² = 154

=> 4×(22/7)×r² = 154

=> r² = 49/4

=> r = 7/2 cm

$So, Volume = \frac{4}{3} \pi {r}^{3} \\ = \frac{4}{3} \times \frac{22}{7} \times { (\frac{7}{2} )}^{3} \\ = \frac{539}{3} \\ = 179.66 {m}^{3}$
