the required volume for this is 8.8

Answer 2

Answer:

hii

your answer is here !

Step-by-step explanation:

Radius of sphere is 2.1 cm

Radius of sphere is 2.1 cm Vol of sphere is 4/3 π r^3

Radius of sphere is 2.1 cm Vol of sphere is 4/3 π r^3 vol. = 4/3× 22/7×2.1×2.1×2.1

Radius of sphere is 2.1 cm Vol of sphere is 4/3 π r^3 vol. = 4/3× 22/7×2.1×2.1×2.1 vol.= 38.808cm cube

Radius of sphere is 2.1 cm Vol of sphere is 4/3 π r^3 vol. = 4/3× 22/7×2.1×2.1×2.1 vol.= 38.808cm cubeNow S.A.= 4πr^2

Radius of sphere is 2.1 cm Vol of sphere is 4/3 π r^3 vol. = 4/3× 22/7×2.1×2.1×2.1 vol.= 38.808cm cubeNow S.A.= 4πr^2 = 4×22/7×2.1 ×2.1

Radius of sphere is 2.1 cm Vol of sphere is 4/3 π r^3 vol. = 4/3× 22/7×2.1×2.1×2.1 vol.= 38.808cm cubeNow S.A.= 4πr^2 = 4×22/7×2.1 ×2.1 =55.44 cm square
