Surface area of a sphere = 4πr2
A blue sphere has a diameter of 4 inches, while a red sphere is half as big with a diameter of 2 inches.
Calculate the volume of the blue sphere in terms of inches cubed (in3), which are the correct units (note, give the answer to the nearest whole number and don't write the units).
Calculate the volume of the red sphere in terms of inches cubed (in3), which are the correct units (note, give the answer to the nearest whole number and don't write the units).
Calculate the surface area of the blue sphere in terms of inches squared (in2), which are the correct units (note, give the answer to the nearest whole number and don't write the units).
Calculate the surface area of the red sphere in terms of inches squared (in2), which are the correct units (note, give the answer to the nearest whole number and don't write the units).
Calculate the surface area of the red sphere in terms of inches squared (in2), which are the correct units (note, give the answer to the nearest whole number and don't write the units).
