surface area of sphere = (4πr2)
so, 4×3.14×[21]2
so, S.A.= 5538.96 sq unit
Vol.is [4/3×π×(21)3]
so, V = 37803.40 cubic unit
hope it help you plz mark as brainliest

Surface area of a sphere=4πr
Surface area of a sphere=4πr 2
Surface area of a sphere=4πr 2 =4×
Surface area of a sphere=4πr 2 =4× 7
Surface area of a sphere=4πr 2 =4× 722
Surface area of a sphere=4πr 2 =4× 722
Surface area of a sphere=4πr 2 =4× 722 ×21×21cm
Surface area of a sphere=4πr 2 =4× 722 ×21×21cm 2
Surface area of a sphere=4πr 2 =4× 722 ×21×21cm 2
Surface area of a sphere=4πr 2 =4× 722 ×21×21cm 2 Surface area of the sphere=5544cm
Surface area of a sphere=4πr 2 =4× 722 ×21×21cm 2 Surface area of the sphere=5544cm 2
Surface area of a sphere=4πr 2 =4× 722 ×21×21cm 2 Surface area of the sphere=5544cm 2 .
