Question

if the surface area of a hemisphere is s them express r in terms of s​

Answer 1

Surface Area = SA

Volume = V

SA = 4π r²

r² = SA / 4π

V = 4/3 π r³

r³ = V / (4/3 π)

r³ = V / (4π / 3)

r³ = V(3/4 π)

r³ = 3V / 4π

r² = (3V / 4π) / r

r² = 3V / 4π r

Answer 2

Step-by-step explanation:

Surface Area = SA 

Volume = V 

SA = 4π r² 

r² = SA / 4π 

V = 4/3 π r³ 

r³ = V / (4/3 π) 

r³ = V / (4π / 3) 

r³ = V(3/4 π) 

r³ = 3V / 4π 

r² = (3V / 4π) / r 

r² = 3V / 4π r
