Given that the radius of the base of the two domes are 21 cm and 42 cm. a) By how much is the volume of the larger dome greater than that of the smaller dome? About the author Iris
Given radius of dome 1= 21 cm radius of dome 2=42 cm To find By how much is the volume of the larger dome greater than that of the smaller Solution volume of dome 1 2/3πr^3 =2/3×22/7×21×21×21 =19,404 cube cm volume of dome 2 =2/3×22/7×42×42×42 =155,232 cube cm difference of there volume volume of dome 2- dome 1 =135,828 cube cm Thanks hope its helpful Reply
Given
To find
Solution
volume of dome 1
2/3πr^3
=2/3×22/7×21×21×21
=19,404 cube cm
volume of dome 2
=2/3×22/7×42×42×42
=155,232 cube cm
difference of there volume
volume of dome 2- dome 1
=135,828 cube cm
Thanks
hope its helpful
