The radius of the moon is 1700 km, and the radius of the earth is 6350 km. a scale model of the earth and the moon is made. in the model, the radius of the moon is 3.4 cm. (i) find the radius of the scale model of the earth. (ii) find the volume of the scale model of the earth.

1) 12.7 cm

2) 8580.24 cm³

Step-by-step explanation:

given,

Radius of moon(Rm) = 1700 Km              Radius of Earth(Re) = 6350 km

Model radius of Moon(Mm) = 3.4 cm        

2) Volume of earth model =

                                       =

                                       = 8580.24 cm³

1) radius of earth =

                        =  

                        = 12.7 cm

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
