Answer: $1296
Step-by-step explanation:
Surface area of s sphere = 4πx r^2
Diameter = 1/2 radius
Surface area = 4π x 12^2
= 1809.56 cm^2 = 18.096 m^2
Material required = 71.62 x 18.096
= $1296
Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.
