radius of a sphere is 5 cm if the diameter is increased by 20% what will be the new radius please fast
radius = 5 cm
so diameter = 2*5 = 10 cm
new diameter = 10 + 20% of 10
= 10 + 20/100 * 10
= 10 + 2
= 12 cm
so new radius = 12/2 = 6 cm
so diameter = 2*5 = 10 cm
new diameter = 10 + 20% of 10
= 10 + 20/100 * 10
= 10 + 2
= 12 cm
so new radius = 12/2 = 6 cm
