Answer: 1.0cm
Explanation:
Given the following :
Volume = Mass / Density
Given that:
Mass of spherical grape = 8.4g
Density = 2g/cm^3
Radius of the grape =?
Volume of grape = mass of grape / density of grape
Volume = 8.4g / 2g/cm^3
Volume = 4.2cm^3
Volume of a sphere = (4/3)πr^3
4.2 = 4/3 * 3.14 * r^3
4.2 = (12 * r^3) / 3
4.2 × 3 = (12 * r^3)
12.6 = 12r^3
r^3 = 12.6/12
r^3 = 1.05
r = 1.01639635681
r = 1.0 cm ( to the nearest tenth)
