Calculate:- area of a square whose side is 1.2 m (2) volume of a sphere whose radius is 1.6 CM (3) length of a rectangle having area 10.25m² and breadth 2.5m About the author Valentina
1) area of square = (side)^2 = (1.2)^2 = 1.44 m^2 2) volume = 4/3 π[tex]r^{3}[/tex] = 17.157 cm^3 3) l*b = area l*2.5 = 10.25 ∴l = 4.1 m Reply
1) area of square = (side)^2 = (1.2)^2 = 1.44 m^2
2) volume = 4/3 π[tex]r^{3}[/tex]
= 17.157 cm^3
3) l*b = area
l*2.5 = 10.25
∴l = 4.1 m
